UNSPSC 31161701: Anchor nuts

UNSPSC 31161701 Anchor nuts is a Commodity code covering the supply of fastening hardware — nuts, washers, and related fasteners — that state and local governments procure as maintenance and operational consumables for infrastructure, transit, and utility systems. Recent solicitations show anchor nuts appearing as line items in broader fastener purchases by transit authorities and water utilities, where they support mechanical assembly, equipment repair, and infrastructure maintenance activities. The Dallas Area Rapid Transit Authority (DART) has posted multiple fastener procurements over the past two months, including elastic stop nuts (1/4-28 zinc-plated), Grade 8 nuts (9/16"-18), and M8 hex fasteners supplied in small packages of 25 to 100 units. These are routine consumables with short lead times and straightforward specification requirements. Issuing bodies soliciting under this code include transit authorities (DART in Texas), municipal water utilities (City of Lavonia, Georgia), and county agencies (Riverside County, California); DART appears as a repeat buyer posting multiple fastener and related-hardware solicitations within a compressed timeframe, suggesting regular maintenance and repair cycles across its vehicle fleet and facility infrastructure.

Activity concentrates in Texas and Georgia, with additional procurement in California. Representative recent opportunities include DART's solicitation for elastic stop nuts 1/4-28 zinc-plated in packages of 100 (posted January 29, 2026, due February 5, 2026) and Grade 8 nuts 9/16"-18 in boxes of 25 (posted January 21, 2026, due January 28, 2026), both requiring FOB Destination pricing with freight included and Net 30 payment terms through the BONFIRE platform. The City of Lavonia water treatment plant expansion (sealed bid, due May 26, 2026, pre-bid conference May 7, 2026) encompasses comprehensive facility upgrades to 3.0 million gallons per day capacity and will incorporate fasteners as components of equipment assembly and mechanical systems, subject to Davis-Bacon prevailing wage and Build America, Buy America (BABA) sourcing requirements with 4.0% DBE participation goals. Riverside County issued an RFB for Cla-Val parts for warehouse inventory (due February 13, 2026), reflecting broader municipal maintenance stocking. DART procurements impose strict delivery schedules, FOB Destination terms, and invoice submission through triplicate documentation to APInvoices@dart.org; no set-aside designations appear in these opportunities, and response windows typically span one to three weeks.
