UNSPSC 31161638: T bolt

A bolt that has a T shaped head.

UNSPSC 31161638 T bolt, a Commodity code, encompasses fastening hardware—specifically T-bolts and associated fastener sets—procured by state and local water utilities and municipalities for infrastructure repair, maintenance, and new construction. Recent solicitations show that state and local governments buy T-bolts as component parts within larger water treatment and distribution system projects, often specified as part of equipment assemblies such as butterfly valve mounting kits and tank or basin connection hardware. Issuing bodies include municipal water districts and city governments operating water infrastructure; the Eastern Municipal Water District (EMWD) in California and the City of Lavonia, Georgia have posted opportunities in the past three months that reference T-bolt specifications as part of broader valve and equipment procurement.

The code shows recent activity in California and Georgia. The Eastern Municipal Water District (EMWD) posted RFQ 3930 on March 17, 2026, for Lineseal XP 36" Butterfly Valves (Class 250B) with gasket and bolt nut sets, with a response deadline of March 20, 2026; the specification explicitly includes fastener sets that would encompass T-bolts sized for the 36-inch valve application. The City of Lavonia, Georgia posted a sealed competitive bid (PE66940NONST2026000000005) on April 24, 2026, for comprehensive Water Treatment Plant 2026 Improvements, with a pre-bid conference on May 7, 2026, and a sealed bid deadline of May 26, 2026; the project scope includes installation of new equipment, modifications to settling basins, filters, and clearwell storage tanks, all of which typically require T-bolt fasteners for assembly and installation. Both opportunities are tied to municipal water infrastructure work rather than standalone fastener procurement, suggesting that T-bolt purchasing under this code typically occurs as part of larger construction or equipment contracts rather than as isolated supply orders.
