UNSPSC 31163201: Spring pins

UNSPSC 31163201 Spring pins, a Commodity code, covers specialized fastening hardware that state and local governments procure as component parts for equipment maintenance, repair, and assembly across diverse operational contexts. Spring pins—coiled or helical fasteners used to secure rotating shafts, transmit torque, or absorb vibration in machinery and mechanical systems—appear in solicitations from transportation authorities, public works departments, facilities management operations, and equipment maintenance programs. The code captures both bulk purchasing of standard spring pin inventory and procurement of engineered pins specified for particular equipment classes, including automotive and transit fleet maintenance, HVAC system repair, and industrial equipment support.

The source provided contains no recent state or local contract opportunities tagged to this code, leaving geographic distribution, issuing-body concentration, and current market activity uncharacterized by recent solicitation data. Without posted opportunities, no representative RFP, RFQ, IFB, or ITB records are available to establish which jurisdictions are actively buying spring pins or at what volume and frequency purchasing occurs under this Commodity code.
