UNSPSC 31161812: Square washers

UNSPSC 31161812 Square washers, a Commodity code, represents fasteners and hardware components that state and local governments procure for maintenance, repair, and construction work. Recent solicitations under this code show state and local bodies buying individual fastener items — bolts, washers, and related hardware — as discrete line-item purchases for fleet maintenance, facilities repair, and infrastructure projects. The issuing bodies include transit authorities and municipal water and utilities departments, purchasing these items through purchase orders and sealed competitive bids as part of larger operational or capital-improvement needs. Work under the code is narrow in scope: individual fasteners specified by size, grade, and material standard, procured in small to moderate quantities with attention to delivery terms, shipping costs, and payment schedules.

Recent activity appears limited. The Dallas Area Rapid Transit Authority (DART) solicited 1/2"-13 X 2-3/4" bolts through purchase order 2100828 with a September 11, 2026 response deadline, requiring FOB Destination shipping with freight included and Net 30 payment terms. The City of Lavonia, Georgia's Water Treatment Plant 2026 Improvements project (sealed bid deadline May 26, 2026) likely required fasteners and hardware as subcomponents of the broader construction scope — filter renovations, chemical feed system upgrades, and tank modifications — but the solicitation itself was not targeted at fastener procurement alone. The code shows little focused recent activity outside the DART purchase order, suggesting that square washers and comparable fasteners are often bundled into higher-tier material or construction solicitations rather than solicited as standalone line items. Activity is concentrated in transit and municipal utilities, primarily in Texas and Georgia.
