UNSPSC 31161710: Expansion nuts

UNSPSC 31161710 Expansion nuts, a Commodity code, addresses fastening components used in state and local infrastructure and utility projects, though recent opportunities reveal the code is being applied primarily to broader construction and facility improvement work rather than discrete fastener procurement. The City of Lavonia, Georgia, posted a sealed competitive bid (IFB) in April 2026 for Water Treatment Plant 2026 Improvements, a nine-month capital project to upgrade treatment capacity to 3.0 million gallons per day, encompassing raw water pump station modifications, new mixing and settling systems, filtration unit renovations, and chemical feed system upgrades across two sites with approximately 1.11 acres of disturbance. The Lavonia opportunity is tagged under this code but represents comprehensive water infrastructure construction rather than expansion-nut procurement specifically — expansion nuts appear as component fasteners within the broader mechanical and structural systems being installed, not as a primary procurement focus.

The geographic and issuing-body activity for this code is sparse in recent state and local records. Lavonia, a municipal water utility in Georgia, stands as the sole recent documented opportunity; no other state departments, counties, school districts, transit authorities, or special-purpose districts appear in the current activity block. The sealed bid deadline was May 26, 2026, with a pre-bid conference held May 7, 2026, and a written question deadline of May 12, 2026. The contract requires a Georgia Utility Contractor license, prevailing wage compliance under Davis-Bacon standards, E-Verify work authorization verification, and compliance with the Build America, Buy America Act; DBE goals specify 4.0% minority-owned and 4.0% women-owned business participation. Contract documents were available from PeoplesQuigley | DCCM for a nonrefundable $250 per set. The mismatch between the code's nominal focus (expansion nuts as discrete fasteners) and the actual solicitation scope (facility construction) signals that state and local procurement activity under this Commodity code is minimal or that issuing bodies are applying it as a catch-all code for infrastructure projects with multiple component categories rather than seeking expansion nuts as a primary line item.
