UNSPSC 31161603: Carriage bolts

UNSPSC 31161603 Carriage bolts is a Commodity code, but the recent state and local procurement activity under this code does not reflect purchasing of carriage bolts themselves. Instead, the tagged opportunities span tubular steel transmission poles, electrical components and fasteners (lugs, bolts, ground rods, couplers, insulators, cables, clamps), inner rings for transit equipment, traffic sign hardware, and water treatment plant construction—none of which are carriage bolts in the traditional sense. The mismatch between the code's nominal scope and actual solicitation activity suggests the code shows little relevant recent purchasing aligned with its stated commodity definition.

The few opportunities tagged under 31161603 come from utility authorities and state transportation agencies. Kissimmee Utility Authority (Florida) issued two separate IFBs for tubular steel transmission poles—Simpson Road Relocation Project (IFB 26-038-JG, closed June 2026) and Marydia to Hansel 69kV Storm Hardening Project (IFB 26-042-JG, due August 2026)—with estimated contract values in the $250,000 to $500,000 range per structure set. The Illinois Department of Transportation posted IFB 27-494DOT-FINAD-B-53545 for District 1 traffic hardware (due October 20, 2026) with a 2% Business Enterprise Program goal. Dallas Area Rapid Transit Authority solicited inner rings via competitive quote (solicitation 2100959, due October 15, 2026), and Lubbock Power & Light (Texas municipal utility) requested quotes on electrical components and fasteners (26-7017-ELD, due October 5, 2026). Activity is concentrated in Florida and Texas, with secondary activity in Illinois. The code appears to be misapplied to infrastructure and electrical component procurements rather than fasteners, limiting its utility as a targeting signal for carriage bolt suppliers.
