UNSPSC 31161714: Insert nuts

UNSPSC 31161714 Insert nuts (Commodity) covers the supply of fastening nuts—elastic stop nuts, hex nuts, suspension spring nuts, and grade-specific variants—that state and local agencies purchase for maintenance, replacement, and operational inventory. Recent solicitations show nuts being bought in bulk packages (25 to 100 units per box) by transit authorities and in smaller volumes by water utilities as components within larger infrastructure projects. The Dallas Area Rapid Transit Authority (DART) is the dominant repeat buyer in the recent record, posting four separate nut and fastener procurement notices between January 21 and January 29, 2026, each specifying distinct nut types and sizes for transit maintenance operations. Beyond DART, the code captures incidental nut procurement within larger construction scopes—the City of Lavonia, Georgia's water treatment plant improvements project, which encompasses raw water pump station modifications and filtration system upgrades, includes fasteners as part of comprehensive infrastructure work. Transit authorities and municipal water utilities represent the primary issuing bodies under this code, with DART's frequency and consistency indicating significant recurring demand for industrial fasteners.

Recent activity concentrates in Texas and Georgia. DART's four January 2026 procurements—elastic stop nuts (1/4-28 zinc, due February 5), hex suspension spring nuts (M8 ESNA, due January 28), grade 8 hex nuts (9/16"-18, due January 28), and cut washers (5/16", due January 29)—establish Dallas County, Texas as the active procurement hub. The City of Lavonia water treatment plant improvements (sealed bid, due May 26, 2026) adds Georgia to the geographic footprint. DART's standardized procurement terms across all four notices require FOB Destination pricing, Net 30 payment, invoice submission to APInvoices@dart.org in triplicate, and BONFIRE platform registration; vendors must certify compliance with Texas foreign terrorist organization and Israel boycott prohibitions. No set-asides or disadvantaged enterprise requirements appear across the recent DART solicitations, indicating open competition. Riverside County, California posted an RFB for Cla-Val parts inventory (due February 13, 2026) that sits tangentially to this code; the mismatch suggests the code sees concentrated, transactional demand from transit authorities rather than broad-based state and local activity.
