UNSPSC 31162211: Solid rivet

A type of rivet consisting of a shaft and head which are deformed with a hammer or rivet gun. The use of a rivet compression or crimping tool can also be used to deform these type of rivets.

UNSPSC 31162211 Solid rivet, a Commodity code, describes fastening hardware state and local governments procure for aircraft maintenance, equipment assembly, and infrastructure repair work. The code covers metallic solid rivets—fasteners driven and deformed to create permanent mechanical joints—used across maintenance and construction operations where temporary or removable fastening is unsuitable. State and local solicitations under this code typically come from transportation departments maintaining vehicle and aircraft fleets, public works agencies, school districts managing facility infrastructure, and transit authorities performing equipment overhaul. The work involves supply of rivets to specification, commonly in aluminum or steel, across a range of diameters and grip lengths suited to the structural or mechanical application.

The source provides no recent state or local contract opportunities under this code, making it difficult to characterize current geographic activity or issuing-body concentration. Without posted solicitations, response dates, or named procurement bodies, the code appears to see minimal or infrequent competitive bidding activity at the state and local level—a signal that most rivet procurement may be consolidated through cooperative purchasing agreements, standing purchase orders with distributors, or embedded within larger equipment-maintenance or repair contracts rather than solicited as discrete fastener buys.
