Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements of Lawson Products, Inc. (the “Company”) have been prepared in accordance with generally accepted accounting principles for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not contain all disclosures required by generally accepted accounting principles. Reference should be made to the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. In the opinion of the Company, all normal recurring adjustments have been made that are necessary to present fairly the results of operations for the interim periods. Operating results for the three and six month periods ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The Company has two operating segments. The first segment, the Lawson operating segment, distributes maintenance, repair and operations ("MRO") products to customers primarily through a network of sales representatives offering vendor managed inventory ("VMI") service to customers throughout the United States and Canada. The second segment, The Bolt Supply House Ltd. ("Bolt Supply") operating segment, distributes MRO products primarily through its branches located in Western Canada. Bolt Supply had 14 branches in operation at the end of the second quarter 2019.

Leases

Leases [Abstract]

Leases

In February 2016 the FASB established Topic ASC 842, Leases, by issuing Accounting Standards Update 2016-02. Lawson adopted ASC 842 as of January 1, 2019. The Company leases property used for distribution centers, office space, and Bolt branch locations throughout the US and Canada, along with various equipment located in distribution centers and corporate headquarters. The Company is also a lessor of its Decatur, Alabama property previously used in conjunction with a discontinued operation, and is a sublessor of a portion of its corporate headquarters.

Lawson Operating Leases

Lawson MRO primarily has two types of leases: leases for real estate and leases for equipment. Operating real estate leases that have a material impact on the operations of the Company are related to the Company's distribution network and headquarters. The Company possesses several additional property leases that are month to month basis and are not material in nature. Lawson MRO does not possess any leases that have residual value guarantees. Several property leases include renewal clauses which vary in length and may not include specific rent renewal amounts. The Company will revise the value of the right of use assets and associated lease liabilities when the Company is reasonably certain it will renew a lease.

The key change commencing on January 1, 2019 for the Company is the recognition of assets and liabilities of operating leases with lease terms longer than twelve months that were not previously capitalized on the balance sheet. The value of the Right Of Use ("ROU") assets and associated lease liabilities is calculated using the total cash payments over the course of the lease, discounted to the present value using the appropriate incremental borrowing rate. The right of use asset will be amortized over its useful life. Similar to deferred rent under ASC 840, the lease liability is reduced in conjunction with the lease payments made, with adjustments made to the lease liability in order to account for non-straight line cash payments through the life of the lease.

Bolt primarily leases the real estate for its branch locations as well as its distribution center in Calgary, Alberta. Bolt possesses additional property leases that are month to month and not material in nature. Bolt property leases include renewal clauses which vary in length and may not include specific rent renewal amounts. The Company will revise the value of the right of use asset and associated lease liability when the Company is reasonably certain it will renew a lease.

Lease of McCook Distribution Facility

Upon adoption of ASC 842, the previously capitalized financing asset and lease liability for the McCook distribution facility was removed from the balance sheet and re-established as a ROU asset and a lease liability as an operating lease. The Company did not include the lease renewal periods in its assessment of the McCook lease as it did not meet the reasonably certain threshold required under ASC 842. Changes in the value of the assets and liabilities associated with the property due to adoption of ASC 842 have been accounted for as an adjustment to beginning retained earnings of $1.9 million.

Accounting Policy Elections

As part of the transition to ASC 842, the Company elected the following practical expedients:

The transitional package of practical expedients as prescribed by ASC 842. Per the practical expedient for the transition to ASC 842, the Company did not reassess expired leases, existing lease classifications or initial indirect costs for existing leases in the calculation of the right to use asset and lease liability.

The Company elected the modified retrospective method of transition, which resulted in no restatement of prior period results with the adoption impact being recorded to opening retained earnings.

The Company did not capitalize short term leases, for all asset classes defined as leases with a term of shorter than twelve months, on the balance sheet. These leases have not been transitioned to ASC 842.

As a practical expedient, the Company did not reassess the accounting for initial direct costs of current leases.

The Company elected not to use the hindsight practical expedient in determining the lease term.

The Company recognizes certain lease components and non-lease components together and not as separate parts of a lease for real estate leases. The Company will exercise this practical expedient in the future by asset class.

Significant Assumptions

The Company is required to determine a discount rate for the present value of lease payments. If the rate is not included in the lease or cannot be readily determined, the Company must estimate the incremental borrowing rate to be used for the discount rate. The Company determined that Lawson MRO and Bolt have different discount rates for leases, as both reporting units have separate borrowing agreements. The Lawson MRO segment will discount the present value of the total payments for the operating and financing leases using the incremental borrowing rate of 5.5%, given the similarity of the lease terms amongst asset classes. The Bolt segment will discount the present value of the total payments of each operating and financing lease at its incremental borrowing rate of 4.2%. The discount rate of Lawson MRO and Bolt will be reviewed on a periodic basis and updated as needed.

Lawson as Lessor

The Company is a lessor of its facility in Decatur, Alabama, which was previously used in conjunction with a discontinued operation. The lease expires in February, 2024. Both the lessor and lessee have a put option to each other upon the completion of the remediation of the environmental matter at a pre-negotiated price less 50% of the rent paid upon the put option being exercised. The net book value at June 30, 2019 is $0.4 million. The Company classifies this lease as an operating lease. The operating lease of the Decatur facility generated approximately $0.1 million of income to the Company for the six months ending June 30, 2019.

Annual lease income classified as operating expenses of $0.2 million is anticipated through the earlier of the put option exercise or February, 2024.

Revenue Recognition

Adoption of ASC 606

On January 1, 2018 the Company adopted Accounting Standards Codification 606-Revenue From Contracts With Customers (“ASC 606”). As part of the Company's adoption of ASC 606, it concluded that it has two separate performance obligations, and accordingly, two separate revenue streams: products and services. As a result, the Company reports two separate revenue streams and two separate costs of revenues.

ASC 606 defines a five step process to recognize revenues at the time and in an amount that reflects the consideration expected to be received for the performance obligations that have been provided. ASC 606 defines contracts as written, oral and through customary business practice. Under this definition, the Company considers contracts to be created at the time an order to purchase product is agreed upon regardless of whether or not there is a written contract.

Performance Obligations

Lawson has two operating segments; the Lawson segment and the Bolt Supply segment. Customer contracts have the following performance obligations:

The Lawson segment has two distinct performance obligations offered to its customers: a product performance obligation and a service performance obligation. Although the Company has identified that it offers its customers both a product and a service obligation, the customer only receives one invoice per transaction with no price breakout between these obligations. The Company does not price its offerings based on any breakout between these obligations.

Lawson generates revenue primarily from the sale of MRO products to its customers. Revenue related to product sales is recognized at the time that control of the product has been transferred to the customer: either at the time the product is shipped or the time the product has been received by the customer. The Company does not commit to long-term contracts to sell customers a certain minimum quantity of products.

The Lawson segment offers a VMI service proposition to its customers. A portion of these services, primarily related to stocking of product and maintenance of the MRO inventory, is provided a short period of time after control of the purchased product has been transferred to the customer. Since some components of VMI service have not been provided at the time the control of the product transfers to the customer, that portion of expected consideration is deferred until the time that those services have been provided.

The Bolt Supply segment does not provide VMI services for its customers or provide services in addition to product sales to customers. Revenue is recognized at the time that control of the product has been transferred to the customer which is either upon delivery or shipment depending on the terms of the contract.

Accounting Policy Elections

The Company has elected to treat shipping and handling costs after the control of the product has been transferred to the customer as a fulfillment cost.

Sales taxes that are imposed on our sales and collected from customers are excluded from revenues.

The Company expenses sales commissions when incurred as the amortization period is one year or less.

Significant Judgments

The Company employs certain significant judgments to estimate the dollar amount of revenue, and related expenses, allocated to the sale of product and service. These judgments include, among others, the percentage of customers that take advantage of the VMI services offered, the amount of revenue to be allocated to the VMI service based on the value of the service to its customers, and the amount of time after control of the product passes to the customer that the VMI service obligation is completed. It is assumed that any customer who averages placing orders at a frequency of longer than 30 days does not take advantage of the available VMI services offered. The estimate of the cost of sales is based on expenses directly related to sales representatives that provide direct VMI services to the customer.

Financial Impact of ASC 606 Adoption

As a result of applying ASC 606 the Company recorded a liability of $0.7 million for deferred revenue on January 1, 2018. Expenses related to these revenues of $0.4 million were also deferred resulting in a net reduction to opening retained earnings of $0.3 million as of January 1, 2018. At June 30, 2019, the Company had a deferred revenue liability of $0.7 million and a deferred expense of $0.3 million for related expenses associated with the deferred service performance obligations, respectively. The deferral of revenue and expenses does not affect the amount, timing and any uncertainty of cash flows generated from operations.

Loan Agreement

Lawson Loan Agreement

In 2012, the Company entered into a Loan and Security Agreement (“Loan Agreement”). The Loan Agreement consists of a $40.0 million revolving line of credit facility, which includes a $10.0 million sub-facility for letters of credit. Certain terms of the original Loan Agreement have been revised by subsequent amendments.

The Loan Agreement, as amended, expires in August 2020. Due to the lock box arrangement and a subjective acceleration clause contained in the Loan Agreement, any outstanding borrowings under the revolving line of credit are classified as a current liability.

Currently, credit available under the Loan Agreement, as amended, is based upon:


a)	85% of the face amount of the Company’s eligible accounts receivable, generally less than 60 days past due, and


b)	the lesser of 60% of the lower of cost or market value of the Company’s eligible inventory, generally inventory expected to be sold within 18 months, or $20.0 million.

The applicable interest rates for borrowings are at the Prime rate or, if the Company elects, the LIBOR rate plus 1.50% to 1.85% based on the Company’s debt to EBITDA ratio. The Loan Agreement is secured by a first priority perfected security interest in substantially all existing assets of the Company. Dividends are restricted to amounts not to exceed $7.0 million annually.

At June 30, 2019, the Company had $6.0 million of borrowings under its revolving line of credit facility and additional borrowing availability of $30.7 million. The Company paid interest of $0.4 million and $0.5 million for the six months ended June 30, 2019 and 2018, respectively. The weighted average interest rate was 4.48% and 3.74% for the six months ended June 30, 2019 and 2018, respectively.

In the second quarter of 2019, the Company's Board of Directors authorized a program in which the Company may repurchase up to $7.5 million of the Company’s common stock from time to time in open market transactions, privately negotiated transactions or by other methods.

In addition to other customary representations, warranties and covenants, if the excess borrowing capacity is below $10.0 million the Company is required to meet a minimum trailing twelve month EBITDA to fixed charges ratio, as defined in the amended Loan Agreement. On June 30, 2019, the Company's borrowing capacity exceeded $10.0 million. Therefore, the Company was not subject to this financial covenant, however, for informational purposes the result of the financial covenant is provided below:



Quarterly Financial Covenant	Requirement	Actual
EBITDA to fixed charges ratio	1.10 : 1.00	7.55 : 1.00

Commitment Letter

Bolt Supply has a Commitment Letter with BMO Bank of Montreal ("BMO") dated March 30, 2017 which allows Bolt Supply to access up to $5.5 million Canadian dollars in the form of either an overdraft facility or as commercial letters of credit. The Commitment Letter is cancellable at any time at BMOs sole discretion and is secured by substantially all of Bolt Supply’s assets. It carries an interest rate of the bank's prime rate plus 0.25%. At June 30, 2019, Bolt Supply had $3.7 million Canadian dollars of outstanding borrowings and remaining borrowing availability of $1.8 million Canadian dollars. The Commitment Letter is subject to a working capital ratio of 1.35:1, a maximum ratio of debt to tangible net worth of 2.5:1 of the Bolt Supply assets and Debt Service Coverage Ratio 1.25:1 as defined in the Commitment Letter.

Stock Based Compensation [Abstract]
Stock Performance Rights	Stock-Based Compensation The Company recorded stock-based compensation expense of $5.2 million and $1.1 million for the first six months of 2019 and 2018, respectively. A portion of stock-based compensation is related to the change in the market value of the Company's common stock. A summary of stock-based awards issued during the six months ended June 30, 2019 follows: Stock Performance Rights ("SPRs") The Company issued 25,793 SPRs to key employees with an exercise price of $30.54 per share that cliff vest on December 31, 2021 and have a termination date of December 31, 2026. SPRs entitle the recipient to receive a cash payment equal to the excess of the market value of the Company's common stock over the SPR exercise price when the SPRs are surrendered. Restricted Stock Units ("RSUs") The Company issued 10,045 RSUs to certain members of the Company's Board of Directors with a vesting date of May 14, 2020. The Company issued 16,781 RSUs to key employees that cliff vest on December 31, 2021. Each RSU is exchangeable for one share of the Company's common stock at the end of the vesting period. Market Stock Units ("MSUs") The Company issued 39,948 MSUs to key employees that cliff vest on December 31, 2021. MSU's are exchangeable for the Company's common stock at the end of the vesting period. The number of shares of common stock that will be issued upon vesting, ranging from zero to 59,922, will be determined based upon the trailing sixty-day weighted average closing price of the Company's common stock on December 31, 2021. No stock options were excluded from the computation of diluted earnings per share for the three months ended June 30, 2019. For the three months ended June 30, 2018, stock options to purchase approximately 80,000 shares of the Company's common stock were excluded from the computation of diluted earnings per share because they were anti-dilutive. For the six months ended June 30, 2019 and 2018, stock options to purchase approximately 9,524 and 63,210 shares of the Company's common stock were excluded from the computation of diluted earnings per share because they were anti-dilutive.

The effective tax rates were higher than the U.S. statutory rate due primarily to state taxes, income in higher tax jurisdictions and an inclusion for global intangible low taxed income. The Company and its subsidiaries are subject to U.S. Federal income tax, as well as income tax of multiple state and foreign jurisdictions. As of June 30, 2019, the Company is subject to U.S. Federal income tax examinations for the years 2015 through 2017 and income tax examinations from various other jurisdictions for the years 2011 through 2018. Earnings from the Company’s foreign subsidiaries are considered to be indefinitely reinvested. A distribution of these non-U.S. earnings in the form of dividends or otherwise may subject the Company to foreign withholding taxes and U.S. federal and state taxes.

Contingent Liability [Abstract]
Environmental Contingency	Contingent Liabilities In 2012, the Company identified that a site it owns in Decatur, Alabama, contains hazardous substances in the soil and groundwater as a result of historical operations prior to the Company's ownership. The Company retained an environmental consulting firm to further investigate the contamination including the measurement and monitoring of the site and the site was enrolled in the Alabama Department of Environmental Management (“ADEM") voluntary cleanup program. The remediation plan was approved by ADEM in 2018. The plan consists of chemical injections throughout the affected area, as well as subsequent monitoring of the area for three consecutive periods. The injection process was completed in the first quarter of 2019 and the environmental consulting firm is monitoring the affected area. The Company made payments of $1.3 million in the first two quarters of 2019 for services rendered by the environmental consulting firm. These payments were applied to the previously accrued environmental remediation liability. The Company believes the remaining environmental remediation liability of approximately $0.1 million, classified within Accrued expenses and other liabilities on the accompanying Consolidated Balance Sheet, will be sufficient to cover the remaining cost of the plan. The Company does not expect to capitalize any amounts related to the remediation plan.

Acquisition

The Company completed the acquisition of Screw Products, Inc. in October 2018 for approximately $5.2 million. The purchase price was funded with cash on hand and utilization of the Company's existing credit facility. Screw Products, Inc. is a distributor of bulk industrial products to large manufacturers and job shops. The Company allocated $2.6 million of the purchase price to an intangible asset for customer relationships and $0.5 million for intangible asset for trade names. These amounts were determined by a third party valuation firm with estimated useful lives of 10 and 15 years, respectively. The excess of the purchase price over the fair values of the identifiable assets and liabilities was recorded as goodwill and represents the expected future benefit to the Company from the acquisition of Screw Products. The Company's Lawson operating segment includes revenues of approximately $0.7 million and $1.5 million from Screw Products in the three and six months ended June, 30 2019, respectively.

The following table contains unaudited pro forma revenue and net income for Lawson Products assuming the Screw Products acquisition closed on January 1, 2018.

Segment Information

The Company operates in two reportable segments. The businesses have been determined to be separate reportable segments because of differences in their financial characteristics and the methods they employ to deliver product to customers. The operating segments are reviewed by the Company’s chief operating decision maker responsible for reviewing operating performance and allocating resources. The Lawson segment primarily relies on its large network of sales representatives to visit the customer at the customers' work location and provide VMI service and produce sales orders for product that is then shipped to the customer. The Bolt Supply segment primarily sells product to customers through its branch locations. Bolt Supply had 14 branches in operation at the end of the second quarter 2019.
