UNSPSC 31163016: Rod coupling

A double-pin-thread coupling used to connect two drill rods.

UNSPSC 31163016 Rod coupling is a Commodity code that covers fastening and mechanical connection components used in facility construction and infrastructure projects. State and local governments procure rod couplings primarily as materials for mechanical systems in building construction, renovation, and infrastructure work — components that connect rods in HVAC systems, structural supports, plumbing installations, and equipment mounting. The issuing bodies soliciting under this code span county departments, municipalities, and special-purpose district authorities managing capital projects.

Recent activity shows limited direct solicitation for rod couplings as standalone line items in state and local procurement. A June 2026 ITB posted by DeKalb County (Georgia) for reconstruction of the DeKalb Tennis Center in Mason Mill Park includes IT and low-voltage infrastructure work with conduit, raceways, cabling, and terminations due July 13, 2026 — a project scope that may encompass rod couplings as incidental fastening materials within the broader mechanical and electrical installation scope, though the solicitation does not isolate the coupling specification. Geographic activity on this code appears concentrated in Georgia based on available recent records. The code shows sparse isolated opportunities rather than a sustained procurement pipeline, indicating that rod couplings typically flow as part of larger materials packages or equipment specifications in building and infrastructure bids rather than as standalone commodity RFQs.
