UNSPSC 31161630: Blank bolt

A semi finished product that is designed to meet the special dimensions of user. If needed, the length may be extended with the outline forming, boring, threading and welding, and others.

UNSPSC 31161630 Blank bolt is a Commodity code that covers fastening hardware used across municipal water and utility infrastructure projects. State and local procurement under this code reflects actual purchases of bolts, nuts, gaskets, and fastener assemblies embedded in larger water treatment and distribution work — not standalone bulk fastener orders. Issuing bodies are primarily municipal water districts and city public works departments managing capital improvements to water systems. The North Texas Municipal Water District Maintenance Department and the City of Lavonia, Georgia (operating under Fayette County jurisdiction) represent the typical buyer profile: mid-sized utilities undertaking facility upgrades or equipment procurement where fasteners appear as line items within broader construction or equipment specifications rather than as primary commodities.

Recent activity clusters in Texas, Georgia, and California. The North Texas Municipal Water District issued an IFB (solicitation 26163B) on July 9, 2026 for two Lincoln Frontier 400X diesel-driven welder/generators due July 29, 2026 — a procurement where fastener kits likely appear in the equipment documentation. The City of Lavonia issued a sealed competitive bid (PE66940NONST2026000000005) on April 24, 2026 for Water Treatment Plant 2026 Improvements due May 26, 2026, a nine-month municipal infrastructure project with modifications to pump stations, mixers, settling basins, filters, chemical feed systems, and clearwell storage that embedded fastener assemblies throughout. The Eastern Municipal Water District (EMWD) in Riverside County, California issued RFQ 3930 on March 17, 2026 for Lineseal XP 36" Butterfly Valves (Class 250B) complete with gasket and bolt nut sets due March 20, 2026 — a direct signal of fastener procurement tied to water distribution equipment. Contractors pursuing this code should expect fasteners to be specified as component parts within larger utility construction, equipment, or valve procurement RFPs and RFQs rather than as standalone supply orders.
