UNSPSC 31163207: Shaft or woodruff keys

UNSPSC 31163207 Shaft or woodruff keys is a Commodity code covering mechanical fastening components — specifically keyed shaft couplings and related hardware — that state and local governments procure as replacement or maintenance parts for rotating machinery, equipment assemblies, and industrial systems. The code captures off-the-shelf fastener inventory that municipalities, counties, state departments, and transit authorities source to support field repairs and preventive maintenance of pump stations, HVAC systems, conveyor equipment, and other shaft-driven industrial infrastructure. Issuing bodies span state departments of transportation and public works, county facilities management offices, municipal water and wastewater utilities, and regional transit authorities that operate bus fleets and rail systems.

The recent-opportunities block contains no posted solicitations under this code, indicating minimal or no current state and local procurement activity in this commodity category. This silence is typical for consumable fastener categories, which state and local buyers often acquire through standing cooperative purchasing agreements, master-supply contracts, or catalog purchases rather than individual competitive solicitations. Firms pursuing sales of shaft and woodruff keys to state and local governments should monitor cooperative-purchasing vehicle catalogs (such as those managed by state procurement consortia), establish relationships with facilities-management cooperatives, and pursue pre-positioned supplier agreements with regional utilities and transit authorities rather than wait for formal RFP or IFB activity under this specific code.
