UNSPSC 31161810: Shim washers

UNSPSC 31161810 Shim washers (Commodity) covers fastening hardware components that state and local governments procure primarily through small goods orders for maintenance, repair, and infrastructure projects. Recent state and local opportunities show two distinct purchase patterns: direct industrial fastening orders (lock washers, shim washers in small packaged quantities) acquired by transit authorities and utilities through competitive bidding, and larger capital construction projects where shim washers and related hardware are specified as incidental components within comprehensive facility upgrades. Issuing bodies include transit authorities (Dallas Area Rapid Transit Authority), municipal water utilities (City of Lavonia, Georgia), and other public infrastructure operators. The code captures routine procurement of standardized fastening supplies by maintenance and engineering departments as well as specification-driven inclusion within broader construction contracts.

Recent activity shows geographic spread across the South, with visible solicitation from Georgia (water treatment facility improvements) and Texas (transit authority fastener procurement). The Dallas Area Rapid Transit Authority issued a purchase order on January 21, 2026 (due January 28, 2026) for Washer Lock 7/16" Medium in packages of 100 units through competitive bidding via the BONFIRE registration system, with FOB Destination shipping and Net 30 payment terms. The City of Lavonia, Georgia posted sealed competitive bidding on April 24, 2026 (due May 26, 2026) for Water Treatment Plant 2026 Improvements, a comprehensive $3 million gallon-per-day capacity upgrade including modifications to settling basins, filtration units, and clearwell storage tanks where shim washers are specified as support hardware; the project requires a Georgia Utility Contractor license, certified Utility Manager employment, prevailing wage compliance, and 4.0% DBE participation goals, with a 270-day construction schedule and $500 per-day liquidated damages for delays.
