UNSPSC 31162300: Mounting hardware

UNSPSC 31162300 Mounting hardware is a Class code. State and local governments under this code procure fasteners and hardware components used in infrastructure, facilities, and equipment assembly — specifically anchor bolts, expansion anchors, post base plates, drive caps, and miscellaneous structural fastening supplies. The purchasing pattern reflects operational supply contracts for public works sign shops, traffic infrastructure, and facility maintenance rather than one-time equipment buys. Issuing bodies span city public works departments, county transportation agencies, and municipal offices of contracting and procurement. The County of Orange in California and the City of Detroit in Michigan are recent active buyers. Scope details from recent solicitations show concrete specifications: the County of Orange's October 2026 IFB seeks 34 line items of steel, aluminum, stainless steel, and galvanized pipes, tubing, bars, sheet metal, and strips with a three-year term and $855,000 aggregate not-to-exceed; the City of Detroit's July 2026 RFQ specifies 5/8" x 3" long thread expansion anchors with hex nut heads in grade 2 zinc finish, hot-rolled pickled and oiled steel post base plates conforming to ASTM specifications, and forged tool steel drive caps. Both contracts require local inventory maintenance, rapid delivery windows, and price parity guarantees against other government buyers.

Recent activity concentrates in California and Michigan, with the largest contract values in California. The County of Orange's metals and hardware IFB closes November 4, 2026 through electronic submission via eProcurement Portal, with Local Small Business and Disabled Veteran Business Enterprise preferences applied; the County imposes a thirty-mile inventory radius requirement around its Public Works facility in Orange and mandates delivery within ten working days. The City of Detroit's anchor bolts and base plates RFQ (rebid version posted September 9, 2026, due September 17, 2026) requires Detroit Based Business Certification as mandatory eligibility, enforces Executive Order 2016-2 workforce composition (50% Detroit residents, 25% minorities, 5% women), and specifies firm fixed pricing with net 30 payment. Both procurements structure terms around three-year initial periods with no automatic renewal, require performance and payment bonds, and impose commercial general liability insurance minimums of $1,000,000 per occurrence.
