UNSPSC 31161618: Threaded rod

UNSPSC 31161618 Threaded rod is a Commodity code covering threaded fastening products and hardware that state and local governments source for vehicle fleet maintenance, transportation infrastructure, and facility operations. The recent solicitations under this code reveal that transit authorities and transportation agencies are buying broad fastener assortments—hex bolts, cap screws, lock nuts, washers, threaded rods, socket cap screws, machine screws, and related hardware—primarily to support fleet vehicle repairs and equipment installation. The Orange County Transportation Authority's IFB 250199 exemplifies the scope: a three-year blanket purchase order for 154 line items of fastening supplies with strict North American sourcing and Grade 8 (10.9 metric) high-strength specifications, requiring monthly deliveries to two facilities and 48-hour response capacity for urgent orders. Issuing bodies under this code include regional transit authorities; the recent opportunities show activity from California and Texas transit systems.

The code shows concentrated recent activity in the Southwest. The Orange County Transportation Authority posted IFB 250199 (due March 16, 2026, with anticipated award April 6, 2026) for $150,000 over three years, with firm fixed unit pricing, 80% weight on total price and 20% on discount from published price lists, Davis-Bacon prevailing wage requirements, and a Disadvantaged Business Enterprise goal. The Dallas Area Rapid Transit Authority issued a separate purchase order (2097740, due February 5, 2026) for rubbing alcohol—a mismatch with the threaded rod code scope—suggesting occasional miscoding in state and local systems. The fastener opportunity at OCTA represents the more decision-relevant recent activity: it requires North American sourcing, ISO 17025 laboratory certifications or MilSpec documentation for bolt compliance, comprehensive inventory tracking, barcode or QR-code product labeling, and commercial general liability insurance of $1 million per occurrence.
