UNSPSC 31161726: Dome nuts

UNSPSC 31161726 Dome nuts is a Commodity code describing fastening hardware—specifically dome-shaped nuts and allied fasteners—that state and local governments procure as consumable supplies for vehicle and equipment maintenance, transit operations, and infrastructure projects. Recent solicitations show dome nuts and related fastening hardware being purchased in modest unit quantities (packages of 25 to 100) alongside other industrial fasteners and specialized parts, with little standalone demand for dome nuts specifically but consistent demand for nuts and fastening hardware as a category. Issuing bodies range from transit authorities to county governments and water utilities, with the Dallas Area Rapid Transit Authority (DART) appearing as a repeat buyer of fastening supplies through routine purchase orders, though dome nuts as a named item do not dominate any single procurement.

Activity concentrates in Texas (DART has posted at least four fastener-related procurements since mid-January 2026) and California (Riverside County RFB for industrial parts inventory posted January 21, 2026, due February 13, 2026), with a single substantial infrastructure project in Georgia (the City of Lavonia water treatment plant expansion, an IFB posted April 24, 2026, with sealed-bid deadline May 26, 2026). DART's January procurements—including solicitations for 1/4-28 elastic stop nuts (January 29, 2026 due date), 9/16"-18 Grade 8 nuts (January 21, 2026 due date), and assorted hex and spring-suspension fasteners (January 21, 2026 due date)—reflect the day-to-day consumables approach typical of transit authorities. All DART procurements require FOB Destination pricing, Net 30 payment terms, and BONFIRE platform registration. The code shows episodic activity rather than sustained or high-volume demand; pursuit depends on capacity to respond rapidly to short-window RFQs and manage small-parcel fulfillment to transit and utility maintenance operations.
