UNSPSC 31161737: Shear nut

Fastening device designed to provide a permanent one way fastening.

UNSPSC 31161737 Shear nut is a Commodity code that covers individual fastening components used in industrial, utility, and infrastructure applications. State and local governments procure shear nuts primarily as component parts within larger construction, maintenance, and equipment-assembly projects rather than as standalone commodity purchases. The code captures fasteners specified in infrastructure upgrades, water and wastewater treatment facility modifications, pump station work, and mechanical systems integration where shear nuts serve critical load-bearing or safety functions. Issuing bodies under this code include municipal utilities, county water authorities, city engineering departments, and special-purpose water districts that source fasteners as part of sealed-bid construction contracts or equipment procurement tied to public infrastructure.

Recent state and local activity under this code is sparse. The most recent identified opportunity is the City of Lavonia, Georgia Water Treatment Plant 2026 Improvements project (Solicitation PE66940NONST2026000000005, sealed competitive bid due May 26, 2026), which encompasses comprehensive facility modifications including pump station work, mixing basin installation, filtration unit renovation, and clearwell tank modifications—scopes where shear nuts would appear as specified fastening components within the broader construction scope. The project spans Lavonia and a remote pump station near Lake Hartwell, requires a Georgia Utility Contractor license, includes prevailing wage and Davis-Bacon compliance, and mandates 4.0% DBE participation and Build America, Buy America compliance. Shear nuts in this context are embedded component-level purchases within the general construction contract rather than standalone solicitations, suggesting that opportunities under this code surface primarily as part of larger infrastructure RFQs or sealed bids where fasteners are specified but not separately itemized or solicited.
