UNSPSC 31161837: Split washer

A type of washer that helps keep a screw from backing out due to vibration.

UNSPSC 31161837 Split washer is a Commodity code that covers industrial fastening hardware components, specifically split washers and lock washers procured by transit authorities and water utilities for maintenance and infrastructure projects. State and local governments purchase these items as consumable parts for equipment assembly, repair, and capital improvement work. The code draws solicitations from transit authorities and municipal water treatment departments, with no dominant repeat buyer evident in recent postings.

Recent activity spans Georgia and Texas, with two representative opportunities posted in early 2026. The Dallas Area Rapid Transit Authority (DART) issued a purchase order on January 21, 2026, with a January 28 response deadline for Washer Lock 7/16" Medium (Package of 100), item number 2097555, a straightforward goods procurement with FOB Destination shipping and Net 30 payment terms. The City of Lavonia, Georgia, posted an IFB on April 24, 2026, with a May 26 sealed-bid deadline for Water Treatment Plant 2026 Improvements (Solicitation PE66940NONST2026000000005), a substantial nine-month construction project that, while primarily a civil infrastructure bid, encompasses ancillary mechanical and fastening hardware as component materials within the broader scope.
