UNSPSC 31161803: Binding washers

UNSPSC 31161803 Binding washers, a Commodity code, encompasses fastening hardware components that state and local governments procure for both routine maintenance and capital infrastructure projects. Recent solicitation activity shows the code capturing a mix of direct goods purchases (industrial fastening hardware like locking washers in standard sizes and quantities) and materials embedded within larger construction or renovation scopes. The buying activity reflects both small-order component replenishment and incorporation into substantial facility upgrades where binding washers support structural or mechanical assembly.

The issuing bodies include transit authorities and municipal utilities. Dallas Area Rapid Transit Authority (DART) posted a purchase order for Washer Lock 7/16" Medium (Package of 100) on January 21, 2026, with a January 28, 2026 response deadline, using competitive sealed bidding on the BONFIRE procurement platform. The City of Lavonia, Georgia posted an IFB for Water Treatment Plant 2026 Improvements on April 24, 2026, due May 26, 2026; while the solicitation encompasses comprehensive construction services, binding washers would be incorporated as materials within the mechanical and structural assembly work. Geographic activity spans Georgia and Texas, with broader representation across states where transit authorities and municipal water utilities manage capital programs. The DART purchase order reflects standard state and local goods procurement terms—FOB Destination freight included, Net 30 payment, timely delivery as essential, and open competitive access with no incumbent or set-aside restrictions disclosed. The Lavonia project is subject to prevailing wage requirements, Davis-Bacon compliance, BABA sourcing rules, and 4.0% DBE/minority/women-owned business participation goals.
