Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying financial statements include the consolidated accounts of The Hillman Companies, Inc. and its wholly-owned subsidiaries (collectively “Hillman” or the “Company”). All significant intercompany balances and transactions have been eliminated. The Hillman Companies, Inc. is a wholly-owned subsidiary of HMAN Group Holdings Inc. (“Holdco”). Affiliates of CCMP Capital Advisors, LLC (“CCMP”) own 79.9% of Holdco's outstanding common stock, affiliates of Oak Hill Capital Partners III, L.P., Oak Hill Capital Management Partners III, L.P. and OHCP III HC RO, L.P. (collectively “Oak Hill Funds”) own 16.8% of Holdco's outstanding common stock, and certain current and former members of management own 3.3% of Holdco's outstanding common stock. For fiscal year 2017, the Company has changed from a calendar year ending on December 31 to a 52-53 week fiscal year ending on the last Saturday in December, effective beginning with the first quarter of 2017. In a 52 week fiscal year, each of the Company’s quarterly periods will comprise 13 weeks. The additional week in a 53 week fiscal year is added to the fourth quarter, making such quarter consist of 14 weeks. The Company’s first 53 week fiscal year will occur in fiscal year 2022. The Company made the fiscal year change on a prospective basis and has not adjusted operating results for prior periods. The change does not materially impact the comparability of quarters or year ended 2017 to the quarters or years ended 2016 or 2015. The adoption of a 52-53 week year was not deemed a change in fiscal year for purposes of reporting subject to Rule 13a-10 or 15d-10; hence, no transition reports are required. In 2017, the Company completed the integration of its All Points subsidiary into the rest of its United States business. After this transition, discrete financial information for the All Points business is no longer regularly reviewed by the Chief Operating Decision Maker. Accordingly, to align the operating segments with the current way management reviews information to make operating decisions, assess performance, and allocate resources, the results of the Company's All Points business are now reported in the United States operating segment. Additional information on the Company's reportable segments is presented at Note 18 - Segment Reporting and Geographic Information. On November 8, 2017, the Company entered into an Asset Purchase Agreement with Hargis Industries, LP doing business as ST Fastening Systems and other related parties, pursuant to which Hillman acquired substantially all of the assets, and assumed certain liabilities, of ST Fastening Systems. ST Fastening Systems, which is located in Tyler, Texas, specializes in manufacturing and distributing threaded self-drilling fasteners, foam closure strips, and other accessories to the steel-frame, post-frame, and residential building markets. Pursuant to the terms of the Agreement, Hillman paid a cash purchase price of $47.2 million. The ST Fastening Systems business is included in the Company’s United States reportable segment. See Note 5 - Acquisitions for additional information. Nature of Operations: The Company is comprised of three separate business segments, the largest of which is (1) The Hillman Group, Inc. (“Hillman Group”) operating primarily in the United States. The other business segments consist of separate subsidiaries of Hillman Group operating in (2) Canada under the names The Hillman Group Canada ULC and H. Paulin & Co., and (3) Mexico under the name SunSource Integrated Services de Mexico S.A. de C.V. In prior years, the Company had operations in Australia under the name The Hillman Group Australia Pty. Ltd. In the year ended December 31, 2016, the Company decided to exit the Australia market following the withdrawal from Australia of a key customer and recorded charges of $1.0 million related to the write-off of inventory and other assets. In the year ended December 30, 2017, the Company fully liquidated its Australian subsidiary and reclassified the cumulative translation adjustment to income. The $638 gain was recorded as other income on the Consolidated Statement of Comprehensive Income (Loss). Hillman Group provides and, on a limited basis, produces products such as fasteners and related hardware items; threaded rod and metal shapes; keys, key duplication systems, and accessories; builder's hardware; and identification items, such as tags and letters, numbers, and signs, to retail outlets, primarily hardware stores, home centers and mass merchants, pet supply stores, grocery stores, and drug stores. The Canada segment also produces fasteners, stampings, fittings, and processes threaded parts for automotive suppliers, industrial Original Equipment Manufacturers (“OEMs”), and industrial distributors.

The accompanying financial statements include the consolidated accounts of The Hillman Companies, Inc. and its wholly-owned subsidiaries (collectively “Hillman” or the “Company”). All significant intercompany balances and transactions have been eliminated.
