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 covering fastening hardware components—washers and related fastening elements—procured by state and local governments for routine maintenance, repair, and capital projects across water infrastructure, transit systems, and facility maintenance operations. State and local issuing bodies soliciting under this code span municipal utilities, transit authorities, and public works departments; recent activity shows both small-volume routine procurement (single purchase orders for fastening hardware) and embedded procurement within larger capital construction projects where fender washers and similar fasteners are specified components of system upgrades.

Recent opportunities reflect this range: the Dallas Area Rapid Transit Authority (DART) posted a purchase order on January 21, 2026, for Washer Lock 7/16" Medium (Package of 100), due January 28, 2026, as a straightforward goods procurement with Net 30 payment terms and FOB Destination shipping required. The City of Lavonia, Georgia, posted a sealed competitive bid on April 24, 2026 (due May 26, 2026) for Water Treatment Plant 2026 Improvements, a nine-month capital project including facility upgrades where fastening hardware such as fender washers are embedded components of equipment installation and piping modifications. Activity is concentrated in the Southeast (Georgia, Texas), with Texas and Georgia representing the most recent posted opportunities. The code shows steady but modest procurement volume, reflecting the commodity's role as a consumable component in larger capital and maintenance contracts rather than as a primary procurement focus.
