UNSPSC 31161717: Wing nuts

UNSPSC 31161717 Wing nuts (Commodity) spans fastener supply to state and local transit authorities and water utilities. Recent opportunities reflect two distinct patterns: Dallas Area Rapid Transit Authority (DART) solicits consumable fasteners—elastic stop nuts, hex nuts, and washers in bulk packages—for vehicle and infrastructure maintenance through routine purchase orders with seven- to fourteen-day response windows. Separately, the City of Lavonia, Georgia, is procuring comprehensive water treatment plant construction services where fasteners and mechanical components are embedded as part of larger capital infrastructure projects rather than standalone acquisitions. The code shows fragmented buying across transit operations (where small-quantity fastener supply is routine) and municipal utilities (where fasteners support capital upgrades). DART appears as a repeat buyer, posting four separate nut and washer solicitations within a ten-day window in late January 2026, signaling ongoing consumable demand for maintenance stock.

Activity is concentrated in Texas and Georgia. DART in Dallas County, Texas, dominates recent posting volume with four commodity fastener procurements (elastic stop nuts 1/4-28, washers 5/16", M8 hex nuts with suspension springs, and Grade 8 nuts 9/16"-18) all due between January 28 and February 5, 2026; all require FOB Destination pricing, Net 30 payment, BONFIRE platform registration, and delivery performance guarantees with potential default termination for schedule delays. Riverside County, California, posted one RFB for Cla-Val parts inventory on January 21, 2026, due February 13, 2026, though specifications and award value are not disclosed in available materials. The Lavonia water treatment project (posted April 24, 2026, sealed bid due May 26, 2026) is construction-focused, requiring Georgia Utility Contractor licensing and Davis-Bacon prevailing wage compliance, with 4.0% DBE participation goals and Build America, Buy America domestic-sourcing requirements—a structural mismatch with the wing nuts commodity code that suggests tagging drift rather than core fastener procurement.
