UNSPSC 31163202: Retaining rings

UNSPSC 31163202 Retaining rings is a Commodity-tier code covering mechanical fasteners and retention devices used in machinery, equipment assembly, and rotating-shaft applications across state and local government operations. State and local procurement offices buy retaining rings as components in maintenance, repair, and capital equipment projects—typically as part of larger mechanical assemblies, replacement-parts orders, or equipment refurbishment contracts rather than as standalone procurements. Issuing bodies span state departments of transportation, facilities management agencies, county maintenance shops, municipal public works departments, and school district maintenance programs that maintain vehicles, HVAC systems, pumps, motors, and industrial equipment.

The source contains no recent state and local contract opportunities tagged to this code. Without posted RFP, RFQ, IFB, or ITB activity, no geographic concentration or representative solicitations can be characterized. Retaining rings typically appear as line items in larger mechanical-repair or parts-and-supplies contracts rather than as the primary procurement driver, which may explain the absence of direct solicitation activity under this specific code. Firms pursuing state and local business in mechanical components and fastener supply should monitor broader equipment-maintenance and repair-parts solicitations where retaining rings would be bundled with related inventory.
