UNSPSC 31163207: Shaft or woodruff keys

UNSPSC 31163207 Shaft or woodruff keys is a Commodity code that covers fastening hardware and mechanical coupling components used in equipment assembly and maintenance. State and local governments soliciting under this code are procuring specialized fasteners, bolts, lugs, couplers, and related hardware for utility infrastructure, fleet maintenance, and facility operations. The issuing bodies include municipal utilities, public safety departments, and city procurement offices that maintain physical infrastructure and equipment across multiple service divisions.

Recent activity shows geographically dispersed solicitation across Texas and Arizona. Lubbock Power & Light, a municipal electric utility in Texas, issued a competitive quote request (solicitation 26-7017-ELD, due October 5, 2026) for 42 line items of electrical components and fastening hardware including lugs, bolts, couplers, insulators, and related materials with quantities ranging from 2 to 2,100 units per item, with delivery to the Erskine Substation and vendor selection weighted on delivery time and pricing. The City of Tucson issued a separate solicitation (260122, due September 17, 2025) for badges, pins, medals, and accessories for public safety departments, which does not align with the shaft or woodruff key commodity scope and appears to represent a classification mismatch in the source data. The code shows material procurement activity among utility operators and municipal maintenance functions in the Southwest, though the volume of recent opportunities is limited to the single substantive fastener solicitation from Lubbock Power & Light.
