UNSPSC 31161731: Weld nuts

Weld nuts have a projection for spot welding. It is classified by function.

UNSPSC 31161731 Weld nuts is a Commodity code nominally identifying fastening components, yet recent state and local solicitations tagged under this code do not reflect fastener procurement — instead, they involve equipment and construction services substantially unrelated to weld nuts themselves. The North Texas Municipal Water District solicited bids for two Lincoln Frontier 400X diesel-driven welder/generator units in July 2026, and the City of Lavonia, Georgia solicited construction services for comprehensive water treatment plant improvements including modifications to pump stations, mixers, basins, filtration systems, and chemical feed systems. This divergence between the code's nominal scope and actual procurement activity suggests the code shows little relevant recent activity for fastener suppliers targeting state and local buyers, as neither opportunity involves the purchase or specification of weld nuts as discrete components.

Water districts and municipal utilities appear in the recent record, but the opportunities tagged under this code do not represent a meaningful market signal for fastener sourcing. The Lavonia procurement, due May 26, 2026, required a Georgia Utility Contractor license, prevailing wage compliance, and 4.0% DBE participation goals, with performance and payment bonds at 100% of contract value — hallmarks of capital infrastructure work, not component supply. Geographic activity appears limited to Texas and Georgia in the available records. Firms pursuing state and local fastener work should verify that opportunities are correctly tagged under fastener commodity codes rather than assume this code reflects genuine weld nut demand.
