UNSPSC 31161732: Half moon nut

A metal fastener largerr than the standard nut with a central, threaded hole that is designed to fit around and secure a bolt or a screw as well as part of the surface where it is placed.

UNSPSC 31161732 Half moon nut, a Commodity code, does not align with the state and local procurement activity posted under it. Of the six recent opportunities tagged with this code, only one appears directly relevant to fastener supply, while the others represent unrelated infrastructure and transit procurement. The Dallas Area Rapid Transit Authority has posted five separate solicitations for various fasteners—elastic stop nuts (1/4-28 zinc), Grade 8 nuts (9/16"-18), M8 ESNA hex suspension fasteners, cut washers (5/16"), and Cla-Val parts—delivered through the BONFIRE platform with FOB Destination terms, Net 30 payment, and strict delivery-schedule enforcement. One substantial procurement posted by the City of Lavonia, Georgia (operating under Fayette County jurisdiction) solicited sealed bids for water treatment plant construction, unrelated to the half moon nut code.

Recent activity concentrates heavily in Texas, driven by DART's recurring consumable fastener purchases posted in late January 2026 with response windows of seven to one week. Riverside County, California posted one RFB for Cla-Val parts inventory with a February 13, 2026 deadline. The source shows no recent procurement activity from state departments, school districts, or other municipal or special-purpose jurisdictions under this code. The DART opportunities dominate: the elastic stop nut solicitation (2097736, due February 5, 2026), the 9/16"-18 Grade 8 nuts (2097554, due January 28, 2026), M8 fasteners (2097609, due January 28, 2026), and cut washers (2097625, due January 29, 2026) all follow identical DART contracting mechanics. The mismatch between the code's nominal scope and the actual posted work—a single marginal fastener procurement among mostly unrelated notices—signals that this code's recent activity does not reflect sustained state and local demand for half moon nuts specifically.
