UNSPSC 31161814: Thrust washers

UNSPSC 31161814 Thrust washers is a Commodity code that captures small precision fastening components used in rotating machinery and mechanical assemblies across state and local infrastructure, equipment maintenance, and transit operations. State and local governments procure thrust washers primarily as maintenance and repair inventory for water treatment facilities, wastewater systems, fleet vehicles, and transit authority rolling stock. The issuing bodies soliciting under this code span transit authorities, municipalities operating utility infrastructure, and public works departments managing mechanical equipment. The code sees activity across multiple states, with recent solicitations originating from Georgia and Texas jurisdictions.

The Dallas Area Rapid Transit Authority (DART) issued a purchase order on January 21, 2026, with a due date of January 28, 2026, for Washer Lock 7/16" Medium (Package of 100), a direct application of thrust-washer-class fastening hardware for transit vehicle maintenance and repair. The City of Lavonia, Georgia, posted a sealed competitive bid (IFB) on April 24, 2026, with a May 26, 2026, deadline for Water Treatment Plant 2026 Improvements—a comprehensive facility upgrade that would include replacement and repair of pump stations, filtration systems, and mechanical equipment where thrust washers serve as wear components. Both solicitations reflect the practical use of this commodity across infrastructure and transit operations: DART's procurement targets immediate maintenance stock, while Lavonia's larger construction project incorporates thrust washers as part of equipment overhauls. The code shows modest but tangible activity in state and local procurement, concentrated in direct-buy and construction-embedded applications rather than large consolidated procurements.
