Basis of Presentation and Summary of Significant Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 1 — 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, 2011. 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-month period ended March 31, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. Certain reclassifications have been made to prior period amounts to conform to current period presentation. Such reclassifications have no effect on net income as previously reported. The Company has adopted Accounting Standards Update (“ASU”) No. 2011-05 and 2011-12 regarding the presentation of comprehensive income in the financial statements. In the first three months of 2012, the effect of restricted share awards and future stock option exercises equivalent to 39 thousand shares would have been anti-dilutive and therefore, were excluded from the computation of diluted earnings per share. There have been no material changes in our significant accounting policies during the three months ended March 31, 2012 as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2011. The Company has determined that there were no subsequent events to recognize or disclose in these financial statements.
