UNSPSC 31161635: Washer assembled bolt

A machine bolt that has is assembled with the washer that cannot be separated for one or more thereof.

UNSPSC 31161635 Washer assembled bolt is a Commodity code that nominally covers fastener hardware components, but the recent state and local procurement activity under this code shows minimal direct relevance to the code's stated scope. The single recent opportunity in the dataset—the City of Lavonia, Georgia water treatment plant improvements project—is a large-scale municipal infrastructure construction contract involving modifications to treatment capacity, pump stations, filtration systems, and chemical feed infrastructure. While such projects typically require fastener materials as incidental components, the primary procurement is construction services, not assembled bolts or washers as standalone line items. State and local governments generally issue this code when purchasing bulk fasteners, hardware kits, or component parts for maintenance, repairs, or assembly operations across water utilities, public works departments, transit authorities, and facilities management operations. The issuing bodies under this code typically include municipal water departments, county public works divisions, and state transportation or facilities maintenance programs.

The City of Lavonia's May 26, 2026 sealed-bid IFB represents the only recent activity captured, with a pre-bid conference scheduled for May 7, 2026. This Georgia-based opportunity suggests regional water utility procurement activity, though the dataset contains no additional Commodity-level opportunities under this code from other states or issuing bodies in the recent period. Without a broader set of recent solicitations, geographic concentration and repeat-buyer patterns cannot be reliably characterized. Firms pursuing assembled-bolt work should monitor smaller maintenance and repair RFQs from water and wastewater utilities, public works departments, and transit systems, where fastener procurement typically appears as line-item purchases rather than as standalone projects of this magnitude.
