UNSPSC 31162422: General fasteners

A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.

UNSPSC 31162422 General fasteners is a Commodity code covering the supply of bolts, nuts, washers, screws, rivets, and related fastening hardware that state and local governments procure for facility maintenance, infrastructure repair, and equipment operations. County facilities management departments and transit authorities are the primary buyers, sourcing fasteners in bulk quantities to support ongoing maintenance of buildings, vehicles, and transit infrastructure. The work ranges from stocking standard commodity fasteners (hex bolts, cap screws, machine screws, lock nuts, flange nuts, washers, threaded rods, socket cap screws, rivets, brass fittings, and hose clamps) to meeting specialized compliance requirements such as North American origin, Grade 8 high-strength specifications, and laboratory or MilSpec certification. Suppliers contract on firm fixed unit pricing with F.O.B. destination delivery terms, maintain scheduled inventory replenishment, and typically accept return of surplus stock with credit. Contracts often include prevailing wage and insurance requirements, and issuers may apply DBE goals or local vendor preferences.

Recent activity centers in California. San Bernardino County Project & Facilities Management issued ITB 6391 in May 2026 for parts and supplies spanning over 500 line items (including fasteners among refrigerants, HVAC components, electrical supplies, plumbing materials, and tools), with a June 19, 2026 response date and a 5 percent local vendor preference. Orange County Transportation Authority issued IFB 250199 in May 2026 specifically for threaded products and fasteners, targeting 154 line items with an estimated contract value of $150,000 over three years through March 31, 2029, a DBE goal (percentage to be determined), North American sourcing and Grade 8 certification mandates, deliveries to two facilities in Orange County, and a March 16, 2026 bid opening date (note: the source date appears inconsistent; anticipated award is stated as April 6, 2026). Both procurements reflect routine ongoing demand from county and transit-authority supply chains with relatively modest individual contract values and competitive low-bid evaluation frameworks.
