UNSPSC 31161708: Channel nuts

UNSPSC 31161708 Channel nuts is a Commodity code covering fastening hardware — specifically nuts, washers, and related components — that state and local governments buy for transit operations, water infrastructure maintenance, and general industrial supply needs. Recent solicitations show channel nuts competing for attention alongside broader fastener procurement, with transit authorities and municipal utilities as the primary buyers. The Dallas Area Rapid Transit Authority (DART) has posted multiple fastener procurements since January 2026, including elastic stop nuts (1/4-28 zinc-plated), Grade 8 hex nuts (9/16"-18), M8 hex fasteners, and cut washers (5/16"), all packaged in quantities of 25 to 100 units for immediate operational use. These are consumable, routine-replacement purchases with short response windows (typically 7–10 days) and strict delivery requirements — vendors must quote FOB Destination with freight included and meet specified delivery schedules or face order rejection and default termination. Payment terms are Net 30 from invoice or order receipt, whichever is later, and all bids require BONFIRE registration and compliance with DART's standard Purchase Order Terms and Conditions.

Recent activity concentrates in Texas and California. DART in Dallas County, Texas, is the dominant repeat buyer, having solicited elastic stop nuts (due February 5, 2026), washers (due January 29, 2026), M8 fasteners with suspension springs (due January 28, 2026), and Grade 8 nuts (due January 28, 2026) across January and February 2026. Riverside County, California, issued an RFB for Cla-Val parts inventory on January 21, 2026 (due February 13, 2026), though the scope is broader industrial components rather than channel nuts specifically. A water-treatment infrastructure project—the City of Lavonia, Georgia, water treatment plant 2026 improvements (sealed bid, due May 26, 2026)—suggests that channel nuts and fasteners may be components within larger construction procurement, though the opportunity summary emphasizes pumps, mixers, filtration, and chemical feed systems rather than fastener supply. The fastener opportunities reflect high-velocity, transactional purchasing with no set-aside designations, no budget disclosure, and commodity-level pricing competition among suppliers.
