UNSPSC 31161801: Locking washers

UNSPSC 31161801 Locking washers, a Commodity code, covers industrial fastening hardware components procured by state and local agencies for maintenance, repair, and construction projects. State and local governments purchase locking washers as discrete inventory items and as components within larger infrastructure and transit-system construction and renovation work. The code attracts purchasing from transit authorities, municipal water utilities, and public works departments acquiring fasteners either through direct goods procurement or as embedded materials in comprehensive facility upgrades.

Recent solicitation activity spans transit and water-utility procurement. The Dallas Area Rapid Transit Authority (DART) posted a purchase order on January 21, 2026 (due January 28, 2026) for Washer Lock 7/16" Medium packages of 100 units as a direct goods procurement through competitive bidding on the BONFIRE registration system, with FOB Destination shipping and Net 30 payment terms. The City of Lavonia, Georgia issued a sealed competitive bid on April 24, 2026 (due May 26, 2026) for a Water Treatment Plant 2026 Improvements project that encompasses comprehensive facility modifications including related appurtenances and fastening hardware; this project, spanning two sites with a nine-month construction schedule and Davis-Bacon prevailing wage requirements, demonstrates locking washers as material components in larger municipal infrastructure work. Geographic activity is concentrated in Texas and Georgia, with both solicitations representing routine maintenance and capital-improvement cycles typical of transit and utility operations.
