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) covers the procurement of high-strength bolts, threaded rods, socket cap screws, hex bolts, lock nuts, washers, rivets, hose clamps, and related fastening hardware that state and local agencies source to support facility maintenance, transit operations, and capital projects. State and local governments buy these items as consumable supplies for recurring use rather than as components integrated into finished goods. The issuing bodies soliciting under the code include county facilities and project management departments, transit authorities, and other public agencies responsible for fleet maintenance and infrastructure upkeep. Quantities range from dozens to hundreds of line items per procurement, with annual estimated usage and three-year contract terms common for high-volume operations.

Orange County Transportation Authority and San Bernardino County represent the recent activity in this Commodity code. Orange County Transportation Authority issued IFB 250199 for threaded products and fasteners with a due date of March 16, 2026, specifying North American-made Grade 8 (10.9 metric) bolts with ISO 17025 certifications or MilSpec documentation; the $150,000 estimated contract value covers a three-year term with deliveries to two facilities in Garden Grove and Santa Ana, California, and includes a Disadvantaged Business Enterprise goal. San Bernardino County Project & Facilities Management issued ITB 6391 for parts and supplies with a due date of June 19, 2026, which encompasses over 500 line items including fasteners, HVAC components, electrical supplies, and plumbing materials; the county offers a local vendor preference of 5 percent. California jurisdictions dominate recent posting activity under this code, with procurement focused on firm-fixed pricing, F.O.B. destination delivery within 14 days to two weeks, and contractual requirements for product certification, inventory tracking, and defect liability.
