UNSPSC 31161712: Flange nuts

UNSPSC 31161712 Flange nuts is a Commodity code that encompasses threaded fasteners with flanged heads used in infrastructure and mechanical assembly applications. Based on recent state and local solicitations, flange nuts appear as component materials within larger construction and renovation projects rather than as primary procurement items. The City of Lavonia, Georgia posted a competitive sealed-bid opportunity in April 2026 for water treatment plant improvements, a project encompassing facility modifications, pump station upgrades, and equipment installation where flange nuts would function as fastening components in piping systems, equipment mounting, and structural assembly. State and local governments procure flange nuts primarily through construction and infrastructure improvement solicitations issued by municipal utilities, water authorities, and public works departments, where they are specified as part of bill-of-materials requirements within broader facility upgrade or maintenance contracts.

The recent activity supporting this code is limited to a single identified solicitation. The City of Lavonia, Georgia (operating under Fayette County jurisdiction) issued an IFB for the Water Treatment Plant 2026 Improvements project with a sealed-bid deadline of May 26, 2026, and a pre-bid conference scheduled for May 7, 2026. The scope included modifications to water treatment capacity, raw water pump station work, and installation of new equipment and systems across two sites. Georgia represents the only state with documented recent activity under this code in the provided data. The procurement requires Georgia Utility Contractor licensing, prevails under Davis-Bacon Act wage standards, and is subject to Build America, Buy America compliance for all iron, steel, and manufactured products. Without additional solicitation records, the decision-relevance and frequency of opportunities under this specific commodity code cannot be assessed beyond this single instance.
