UNSPSC 31161639: Hanger bolt

A headless bolt that is designed to connect a round bar and hanger to tie up to the ceiling.

UNSPSC 31161639 Hanger bolt is a Commodity code that captures fastening hardware used in construction and facility maintenance projects, though the recent state and local procurement activity under this code shows limited direct solicitation for hanger bolts as a standalone line item. State and local governments acquire hanger bolts primarily as components within larger construction and infrastructure projects rather than through discrete fastener procurements. The issuing bodies pursuing work under this code include municipal water authorities and public works departments managing utility infrastructure upgrades. Hanger bolts serve as support hardware in mechanical systems, structural connections, and equipment mounting applications common to water treatment facilities, building systems, and other municipal infrastructure.

The City of Lavonia, Georgia, issued a sealed competitive bid on April 24, 2026 (due May 26, 2026) for Water Treatment Plant 2026 Improvements, a comprehensive nine-month construction project to increase treatment capacity to 3.0 million gallons per day. The scope includes modifications to raw water pump stations, flash mixers, settling basins, filtration units, chemical feed systems, and clearwell storage tanks—all of which incorporate hanger bolts and similar fastening hardware as components of equipment mounting and structural support systems. The project requires a Georgia Utility Contractor license, Davis-Bacon prevailing wage compliance, and Build America, Buy America Act adherence, with 4.0% disadvantaged business enterprise participation goals. A pre-bid conference was scheduled for May 7, 2026, and written contractor questions were due by May 12, 2026. Beyond this single recent opportunity, the source reflects limited discrete activity in hanger bolt procurement at the state and local level; most procurement under this code appears embedded within larger construction contracts rather than issued as standalone fastener RFQs or ITBs.
