UNSPSC 31161627: Bolt assembly

A mechanism consisting of a threaded bolt with various head configurations and including other components such as sleeves, expansion devices, etc.

UNSPSC 31161627 Bolt assembly is a Commodity code that encompasses fasteners and hardware components used across diverse state and local infrastructure and utility operations. Recent solicitations show state and local governments buying bolts, lugs, fasteners, and related hardware as discrete line items or as components integrated into larger transmission, electrical, and traffic equipment procurement. The issuing bodies include municipal utilities (Kissimmee Utility Authority, Lubbock Power & Light), transit authorities (Dallas Area Rapid Transit Authority), state transportation departments (Illinois Department of Transportation), and water utilities (City of Lavonia). While the code's nominal scope is bolt assembly, the actual buying activity reflects procurement of individual fastener components and hardware kits rather than complete pre-assembled bolt units; vendors respond to component-level specifications with quantities ranging from a handful of units to over 2,000 per line item.

Recent activity spans Florida, Texas, Illinois, and Georgia. The Kissimmee Utility Authority has posted multiple IFBs for tubular steel transmission poles (IFB 26-042-JG posted October 19, 2026, with bids due August 25, 2026, and a closed IFB 26-038-JG) that specify bolts and fasteners as integral components; the Simpson Road Relocation Project bid closed in June 2026 with four respondents and an estimated contract value of $250,000 to $500,000. The Dallas Area Rapid Transit Authority issued an IFB for inner ring components (part number 2100959) due October 15, 2026. The Illinois Department of Transportation (IDOT) solicited hardware for District 1 traffic needs (IFB 27-494DOT-FINAD-B-53545) due October 20, 2026, with a 2% Business Enterprise Program goal. Lubbock Power & Light, a Texas municipal utility, requested quotes on 42 line items including bolts, lugs, and fasteners (RFQ 26-7017-ELD) with a three-quote competitive process and October 5, 2026 deadline. Delivery terms consistently emphasize FOB destination compliance, firm freight pricing, and adherence to strict schedules; payment terms typically run Net 30 and invoicing is material to performance evaluation.
