UNSPSC 31163010: Spider coupling

A connecting device used on shafts of rotary machines to make connections. It is star or spider shaped, elastic but very resistant.

UNSPSC 31163010 Spider coupling is a Commodity code. State and local government procurement under this code shows little relevant recent activity. The source opportunities tagged to this code involve anchoring and buoy components (City of Philadelphia), traffic sign hardware and brackets (City of Indianapolis), telecom parts and tools (Texas Health and Human Services Commission), silo accessories (City of Philadelphia), door parts and locks (Texas HHS), walk-in building supplies (State of Oregon cooperative purchasing), woodshop and food service consumable supplies (Texas HHS), maintenance tools and hardware (Texas HHS), janitorial and operational supplies (Hillsborough County), HVAC parts and furnishings (Texas HHS), station alerting audio parts (City of Austin), and law enforcement equipment (Sourcewell cooperative). None of these align with spider coupling procurement — a mechanical fastening or flexible coupling component used in rotating-shaft applications, typically purchased as a single product line rather than bundled with structural hardware, facility accessories, or consumable supplies.

The disconnect between the code's nominal scope and the recent opportunities suggests either a cataloging error in the source data or that spider couplings are not currently being solicited as a standalone commodity by state and local procurement offices. Firms pursuing work in this commodity should monitor cooperative purchasing agreements and blanket-order frameworks with Texas HHS and other states' facilities maintenance programs, as coupling components may surface in future maintenance and repair solicitations. Until relevant opportunities appear, this code warrants a watch rather than active pursuit.
