UNSPSC 31163304: Complex stud

A stud like component with other than straight shaft or other complex physical characteristics

UNSPSC 31163304 Complex stud is a Commodity code that in recent state and local procurement covers fastening supplies and related hardware — a broader category than the code name alone suggests. The Orange County Transportation Authority's March 2026 IFB for threaded products and fasteners illustrates the actual scope: hex bolts (SAE and metric), cap screws, lock nuts, flange nuts, washers, threaded rods, socket cap screws, machine screws, rivets, brass fittings, and hose clamps, with stringent sourcing and quality requirements including North American origin and Grade 8 / 10.9 metric certification. State and local issuers pursuing this code include transportation authorities (the primary visible buyer in recent notices), though the code likely spans procurement at county and municipal maintenance operations as well. The landscape shows limited recent activity under this code — only one clearly on-point opportunity appears in the recent record, suggesting either narrow demand or inconsistent coding of fastener procurement across jurisdictions.

The Orange County Transportation Authority's threaded products and fasteners IFB 250199 (response due March 16, 2026, contract value $150,000 over three years) represents the main active opportunity geographically centered in California. The second recent posting tagged to this code — Dallas Area Rapid Transit's rubbing alcohol procurement — falls outside the scope of complex studs or fastening hardware and reflects a coding mismatch rather than a representative opportunity. The OCTA solicitation emphasizes compliance with Davis-Bacon wage requirements and California labor standards, monthly scheduled delivery to two facilities in the Los Angeles area, and 48-hour response capability for urgent orders. Disadvantaged Business Enterprise goals apply to the OCTA award. With only one genuine opportunity visible in the recent window, state and local demand under this code appears concentrated and episodic rather than broad-based across regions.
