UNSPSC 31161740: Bolt nut

A combined component used to tighten down on the bolt shaft.

UNSPSC 31161740 Bolt nut is a Commodity code under which state and local governments purchase small fasteners—nuts of specific thread sizes, materials, and configurations—primarily for maintenance, repair, and capital projects. Recent solicitations show that transit authorities are the primary buyers of nuts under this code, with Dallas Area Rapid Transit Authority posting RFQs for stainless steel structural nuts (5/8"-11 right-hand jam thread) and slotted stainless steel nuts (#10-24), both due in May and August 2026. The work is straightforward supply procurement: vendors respond to quotes with FOB Destination terms, freight included, Net 30 payment, and strict adherence to specified delivery schedules as a condition of performance. DART's repeated posting of nut solicitations suggests ongoing replenishment demand across the transit maintenance cycle. The code appears to serve primarily as a component supply category rather than a major capital driver; no set-aside designations or disadvantaged-enterprise requirements are noted in the DART solicitations.

Dallas Area Rapid Transit Authority in Dallas County, Texas, dominates the recent activity on this code, with two posted RFQs within a four-month window. A third opportunity posted by the City of Lavonia, Georgia, for Water Treatment Plant improvements in April 2026 does not reflect genuine activity under this code—the procurement is classified as construction services and does not involve fastener supply. The geographic concentration on Texas transit procurement and the tight response windows (one week from posting) signal that vendors in or capable of rapid delivery to the Dallas area hold an operational advantage. Current activity is limited; the source does not support pending or planned solicitations beyond the closed May and August 2026 deadlines.
