UNSPSC 31161823: Fender washer

A type of washer that is much larger in diameter than the bolt with which it is used. This gives the washer the ability to distribute the bolt force over a wider area.

UNSPSC 31161823 Fender washer is a Commodity code capturing fastener hardware that state and local governments procure for maintenance, repair, and construction applications. State and local purchasing under this code centers on standard fasteners — bolts, washers, and related hardware — acquired through purchase orders and sealed competitive bidding for fleet maintenance, facility upkeep, and infrastructure projects. Transit authorities, city public works departments, and water utilities are the primary issuing bodies, typically sourcing fasteners in small to moderate volumes through straightforward procurement vehicles with short lead times and Net 30 payment terms.

The code shows activity concentrated in the South, with documented recent solicitations from the Dallas Area Rapid Transit Authority (DART) in Texas and the City of Lavonia, Georgia. DART posted a purchase order for 1/2"-13 X 2-3/4" bolts (Solicitation 2100828) with a due date of September 11, 2026, requiring FOB Destination pricing with freight included and Net 30 invoicing submitted to APInvoices@dart.org. The City of Lavonia's Water Treatment Plant 2026 Improvements project (Solicitation PE66940NONST2026000000005), due May 26, 2026, encompasses construction services that would incidentally procure fasteners and hardware as subcomponents of larger infrastructure upgrades. Fastener procurement under this code typically moves quickly—DART's bolt solicitation allowed one week for bid response—and operates under standard commercial terms without set-asides or prevailing-wage requirements specific to the hardware itself, though larger projects may impose Davis-Bacon compliance on overall construction work.
