UNSPSC 31161607: Expansion bolts

UNSPSC 31161607 Expansion bolts is a Commodity code that describes fasteners used in utility infrastructure, transmission, and electrical equipment assembly — though recent state and local opportunities show the code capturing a broader range of hardware procurement than its narrow title suggests. State and local governments buying under this code include municipal utility authorities, regional transit agencies, state transportation departments, and municipal electric utilities. The work spans tubular steel transmission pole construction, electrical substation equipment assembly, traffic control hardware maintenance, and general utility infrastructure fastening. Kissimmee Utility Authority has posted at least two separate IFBs for transmission structures — the Simpson Road Relocation Project (IFB 26-038-JG, closed June 30, 2026, estimated value $250,000 to $500,000) and the Marydia to Hansel 69kV Storm Hardening Project (IFB 26-042-JG, response due August 11, 2026) — both involving tubular steel poles with specialized bolting, fastening, and structural hardware. Dallas Area Rapid Transit Authority solicited inner rings and related fasteners (RFQ 2100959, due October 15, 2026), while Lubbock Power & Light requested quotes on bolts, lugs, fasteners, and ancillary electrical hardware (26-7017-ELD, due October 5, 2026).

Activity concentrates in Florida, Texas, and Illinois. The Illinois Department of Transportation (IDOT) issued IFB 27-494DOT-FINADB53545 for District 1 traffic hardware — bolts, fasteners, and related items for sign repair and maintenance — with bids due October 20, 2026 and a 2% Business Enterprise Program goal. Most recent opportunities carry firm or estimated fixed pricing, FOB Destination terms, strict delivery schedules (DART emphasizes delivery timing as material to contract performance; IDOT requires 30 business days from order), and mandatory inspection and acceptance protocols. Cooperative purchasing is present: Sourcewell issued RFP 061626 for law enforcement equipment on behalf of participating entities including Washington counties, expanding the addressable market beyond single jurisdictions. Performance bonds, liability insurance ($1 million per occurrence minimum for IDOT), and vendor disclosure documentation are standard requirements. The code shows active, recurring procurement with tight response windows and emphasis on delivery performance and material conformance.
