UNSPSC 31161806: Finishing washers

UNSPSC 31161806 Finishing washers (Commodity) covers industrial fastening hardware, specifically lock washers and related fastening components procured by state and local governments for fleet maintenance, facility operations, and infrastructure projects. Recent solicitations show state and local buyers purchasing finishing washers as consumable inventory components — bulk packages of lock washers in standard sizes (7/16" medium format) — used in mechanical assembly and repair work across transit systems, water treatment facilities, and municipal operations. The code spans both small-value purchase orders for individual hardware items and larger infrastructure projects where finishing washers are specified components in construction and equipment installation work.

State and local issuing bodies pursuing this code include transit authorities and municipal water utilities. The Dallas Area Rapid Transit Authority (DART) issued a purchase order for Washer Lock 7/16" Medium (Package of 100) on January 21, 2026, with a response deadline of January 28, 2026, procured through the BONFIRE registration system under Net 30 payment terms with FOB Destination shipping required.
