UNSPSC 31161729: Knurled nuts

UNSPSC 31161729 Knurled nuts is a Commodity code that captures fastener components used across state and local infrastructure, facilities, and maintenance projects. Despite the specific technical name, the code's application in state and local procurement spans general-purpose fastening hardware incorporated into larger construction and renovation work rather than knurled nuts as standalone line-item purchases. State and local governments procure under this code primarily through municipal water and wastewater authorities, county public works departments, and city capital project offices that bundle fastener requirements into broader construction and infrastructure modernization contracts. The issuing bodies tend to be municipal utilities and city engineering departments managing facility upgrades and infrastructure improvements that incorporate standardized hardware components as part of the bill of materials.

The City of Lavonia, Georgia (operating under Fayette County jurisdiction), posted a sealed competitive bid (IFB) on April 24, 2026, for Water Treatment Plant 2026 Improvements, with a response deadline of May 26, 2026. The project encompasses comprehensive modifications to an existing water treatment facility to increase treatment capacity to 3.0 million gallons per day, including modifications to the raw water pump station at Lake Hartwell, installation of new mixing basins and plate settler systems, renovation of four filtration units, upgrades to the chemical feed system, and modifications to clearwell storage tanks. Work spans two sites approximately 14 miles apart with a construction schedule of approximately nine months. The solicitation requires a Georgia Utility Contractor license, compliance with prevailing wage standards under the Davis-Bacon Act, 4.0% DBE participation goals for minority- and women-owned businesses, and adherence to the Build America, Buy America Act with U.S.-origin materials unless a waiver is obtained. A pre-bid conference is scheduled for May 7, 2026, with written contractor questions due by May 12, 2026. This represents the primary recent state and local activity posted under the code, suggesting limited current procurement volume targeting knurled nuts specifically at the commodity line-item level.
