UNSPSC 31161824: Roof bolt washer

Large washers used in conjunction with roof bolt to support roof in underground mining.

UNSPSC 31161824 Roof bolt washer is a Commodity code that captures fastening hardware used across state and local infrastructure and utility construction projects. Recent solicitations show the code applied to both large-scale municipal water treatment facility upgrades and routine transit authority parts procurement, reflecting a wide range of small-parts applications in public-sector maintenance and capital projects. State and local governments buy these components as part of comprehensive construction contracts, facility modifications, and discrete purchase orders for replacement inventory; the actual work spans from major infrastructure overhauls requiring hundreds of fastening components to routine replenishment orders for transit and utility systems.

The City of Lavonia, Georgia (posting April 2026, sealed bid deadline May 26, 2026) solicited construction services for a Water Treatment Plant 2026 Improvements project that includes modifications to treatment capacity, pump stations, settling basins, and filtration units—work that would incorporate fastening hardware as part of broader facility upgrades. The Dallas Area Rapid Transit Authority (DART, posting January 2026, deadline January 28, 2026) issued a straightforward purchase order for Washer Lock 7/16" Medium packages, representing routine parts procurement. These two opportunities signal activity in Georgia and Texas; the code shows sparse recent activity overall, with solicitations fragmented across different issuing-body types (municipal water utilities and regional transit authorities) rather than concentrated in any single jurisdiction or agency.
