UNSPSC 31162423: Special fasteners

Special fasteners refer to a type of fastening hardware that is designed for specific applications and requirements. They are typically made to order or custom-made according to the specifications of the application. Unlike standard fasteners, which have standard dimensions and are readily available, special fasteners are unique and have specific features that meet the needs of the application. Temporary fasteners are designed specifically to join two materials or objects, with the option to be removed and reused without damaging the objects they hold together.

Common examples include bolts, screws, nuts, washers and studs.

UNSPSC 31162423 Special fasteners (Commodity) encompasses high-strength threaded products and specialized fastening supplies procured by state and local governments for facility maintenance, fleet operations, and infrastructure repair. Recent state and local solicitations show demand for 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, typically specified to North American origin (USA, Canada, or Mexico) and Grade 8 (10.9 metric) standards. County transportation authorities and facility management departments are the primary issuing bodies under this code, procuring fasteners in bulk quantities under multi-year supply agreements with firm fixed pricing and responsive delivery requirements, including 48-hour urgent fulfillment and three- to ten-business-day lead times for stocked and non-stock items.

California dominates recent activity, with the Orange County Transportation Authority (OCTA) issuing IFB 250199 for threaded products and fasteners on May 1, 2026, due March 16, 2026 (note: discrepancy in posted and due dates suggests the opportunity may have been reprinted or reposted), valued at $150,000 over three years with deliveries to Garden Grove and Santa Ana facilities and a Disadvantaged Business Enterprise goal applied; and San Bernardino County Project & Facilities Management posting ITB 6391 on May 18, 2026, with response due June 19, 2026, requesting pricing on a minimum of 20 items from a 500-line-item catalog encompassing fasteners, HVAC components, electrical supplies, and building materials. Both solicitations require firm-fixed unit pricing on an F.O.B. destination basis with no escalation permitted during contract term. OCTA's procurement includes Davis-Bacon prevailing wage requirements, California Labor Code compliance, and $1 million/$2 million Commercial General Liability insurance; San Bernardino County offers a 5 percent local vendor preference for businesses within county boundaries.
