UNSPSC 31161812: Square washers

UNSPSC 31161812 Square washers, a Commodity code, encompasses industrial fastening hardware — washers and related components — that state and local governments procure for maintenance, repair, construction, and capital projects. Recent solicitations show state and local bodies buying both individual fastener items (lock washers in specific sizes and quantities) and washers as incidental line items within broader infrastructure construction contracts. The issuing bodies include transit authorities, city water and utility departments, and county-level infrastructure agencies. The work itself ranges from routine purchase orders for off-the-shelf fastening supplies to incorporation of washers and hardware as component specifications within large-scale construction scopes.

Activity under the code appears limited and dispersed across geographies and issuing bodies. The Dallas Area Rapid Transit Authority (DART) posted a straightforward purchase order for Washer Lock 7/16" Medium (Package of 100) with a response deadline of January 28, 2026, under open competitive procurement with Net 30 payment terms and FOB Destination shipping required. The City of Lavonia, Georgia, issued a sealed competitive bid (due May 26, 2026) for Water Treatment Plant 2026 Improvements, a substantial infrastructure project that encompasses washers and fasteners as components within a comprehensive facility renovation but does not isolate them as a primary procurement focus. The code shows no concentrated buying pattern among a repeat set of issuers or within a single state, and opportunities are sparse relative to the breadth of state and local procurement activity overall.
