UNSPSC 31161600: Bolts

UNSPSC 31161600 Bolts, a Class code, covers fasteners and connectors purchased by state and local governments primarily for utility infrastructure, traffic safety, and equipment maintenance. Recent solicitations show state and local buyers acquiring bolts as components within larger procurements—transmission pole assemblies for electric utility storm-hardening projects, inner rings and hardware for transit authority vehicle maintenance, guardrail systems for highway departments, electrical equipment packages for municipal utilities, and specialized fastener sets for water treatment facility construction. The code captures both standalone fastener orders and bolts embedded within broader materials and hardware buys. Issuing bodies include municipal electric utilities (Kissimmee Utility Authority, Lubbock Power & Light), transit authorities (Dallas Area Rapid Transit Authority), state transportation and procurement departments (Illinois Department of Transportation, California Department of General Services), county public works offices (Orange County, California), and state agencies managing infrastructure (California Department of Food and Agriculture for equipment support). Repeat buyers in the recent data include Kissimmee Utility Authority, which has posted two transmission pole procurements in the past four months.

Geographic activity concentrates in Florida, Texas, California, and Illinois. Representative recent opportunities include Kissimmee Utility Authority's IFB 26-042-JG for tubular steel transmission poles (bids due August 11, 2026, though posted October 19, 2026 with a delivery deadline of July 1, 2027), which encompasses eight custom structures requiring transmission-grade bolts and hardware; Dallas Area Rapid Transit Authority's solicitation 2100959 for inner rings and fasteners (quotes due October 15, 2026, with FOB Destination delivery and Net 30 payment terms); Orange County Public Works' IFB-080-3113903 for various metals and related hardware covering 34 line items including bolts and fasteners (bids due November 4, 2026, aggregate contract value not exceeding $855,000, with a three-year initial term and local small-business and disabled-veteran preferences); and Illinois Department of Transportation's IFB 27-494DOT-FINADB53545 for District 1 traffic hardware including fasteners (bids due October 20, 2026, with a 2% minority/women/disability-owned business goal). Delivery windows are typically 10 to 30 business days, FOB Destination terms are standard, and performance and payment bonds are frequently required on larger contracts.
