UNSPSC 31163200: Retaining hardware

UNSPSC 31163200 Retaining hardware is a Class code encompassing fasteners, connectors, and securing components that state and local governments procure for infrastructure maintenance, utility operations, and equipment assembly. Recent solicitations show state and local buyers acquiring lugs, bolts, anchor bolts, couplers, clamps, ground rods, insulators, and related electrical and mechanical fastening materials in quantities ranging from dozens to thousands of units per item. Municipal utility districts, city departments, and public safety agencies use this code when sourcing replacement and maintenance stock for electrical substations, power distribution systems, and facility infrastructure. The work is straightforward procurement of commodity hardware against technical specifications and bill-of-materials lists, with vendors typically quoting on item-by-item or all-or-none bases and competing on price, delivery time, and availability.

Lubbock Power & Light, the municipal electric utility in Texas, posted a competitive quote request (RFQ) in late September 2026 seeking 42 line items of electrical fasteners and hardware for the Erskine Substation with a response date of October 5, 2026. The City of Tucson posted an RFP in August 2026 for badges, pins, and medals for public safety departments with a September 17, 2025 response date, which appears tagged to this code but falls outside the typical retaining hardware scope. Recent activity concentrates in Texas and Arizona, though geographic spread data is limited to these two recent postings. Lubbock Power & Light required FOB destination pricing with freight prepaid, Material Safety Data Sheets for hazardous materials, and ten-day firm quote validity, with delivery time factored into award decisions and the option to pay via purchasing card.
