UNSPSC 31161804: Curved washers

UNSPSC 31161804 Curved washers is a Commodity code covering fastening hardware components that state and local governments procure for maintenance, repair, and infrastructure projects. Recent opportunities show the code sees mixed usage — some solicitations seek curved washers as discrete goods purchases (small-volume fastener orders for transit and municipal operations), while others tag infrastructure projects that incidentally require washers as part of larger construction or equipment-modification scopes. The issuing bodies include transit authorities, municipalities, and water utilities. The City of Lavonia, Georgia water treatment facility expansion (posted April 2026, sealed-bid deadline May 26, 2026) encompasses plant modifications including new equipment installation and chemical feed system upgrades—work that would necessarily include fastening hardware but was tagged under this code despite its primary scope being civil construction. Dallas Area Rapid Transit Authority (DART) posted a direct goods procurement for Washer Lock 7/16" Medium in January 2026 (deadline January 28, 2026), illustrating the code's application to straightforward industrial fastener stock replenishment.

Geographic activity centers on the Southeast (Georgia) and Texas, with recent solicitations posted in early 2026. The Lavonia water treatment project, funded partly through Georgia's Environmental Finance Authority State Revolving Fund and subject to Build America, Buy America requirements, required sealed competitive bidding with a pre-bid conference scheduled for May 7, 2026, and a nine-month construction window. DART's fastener purchase order required FOB Destination pricing, Net 30 payment terms, and timely delivery performance, with submissions via the BONFIRE online bidding platform. Both opportunities reflect standard state and local competitive procurement practices with full compliance documentation, bonding, and prevailing-wage or commercial-warranty obligations as applicable.
