UNSPSC 31161827: Clipped washer

A type of washer used when there is not enough room for a standard washer and also the washer will not rotate.

UNSPSC 31161827 Clipped washer is a Commodity code that encompasses fastener components — specifically washers designed to prevent fastener rotation or spread loads — that state and local governments procure for vehicle maintenance, transit infrastructure repair, water treatment facility construction and modification, and general facility upkeep. Recent solicitations show transit authorities and municipalities buying clipped washers as part of larger procurement packages for infrastructure projects and routine maintenance operations, often bundled with bolts, nuts, and related hardware.

Transit authorities and municipalities account for the issuing-body activity under this code. The Dallas Area Rapid Transit Authority (DART) in Texas has posted procurement activity for fastener components in the most recent window. The City of Lavonia, Georgia, in partnership with Fayette County, has solicited construction services for water treatment plant improvements that include associated fastener and hardware needs as part of the overall project scope.

Activity appears concentrated in Texas and Georgia based on the most recent opportunities. DART issued Purchase Order 2100828 on September 3, 2026, requesting bids on bolts (1/2"-13 X 2-3/4") with a response deadline of September 11, 2026, using a competitive sealed-bid process in the BONFIRE platform; payment terms are Net 30 with FOB Destination shipping required. The City of Lavonia issued a sealed competitive bid (PE66940NONST2026000000005) on April 24, 2026, for Water Treatment Plant 2026 Improvements, due May 26, 2026, which encompasses facility modifications including associated hardware and fastener components; the project requires a pre-bid conference on May 7, 2026, and carries a nine-month construction schedule with 4.0% disadvantaged business enterprise participation goals and Davis-Bacon prevailing wage requirements.
