UNSPSC 31161723: Nutplate nuts

UNSPSC 31161723 Nutplate nuts is a Commodity code. State and local governments procure fastening hardware—elastic stop nuts, hex nuts, Grade 8 nuts in various thread sizes and finishes—for transit operations, water treatment infrastructure, and general maintenance inventory. The Dallas Area Rapid Transit Authority (DART) is the dominant recent buyer, issuing multiple purchase orders for nuts in 1/4-28 zinc, M8 stainless steel, and 9/16"-18 Grade 8 specifications packaged in quantities of 25 to 100 units. Riverside County, California has also posted a competitive bid for Cla-Val parts inventory. These solicitations reflect routine consumable replenishment—nuts and fasteners required as replacement or maintenance stock for fleet and facility operations. DART's procurement patterns show short response windows (typically seven to two weeks) and require vendors to register on the BONFIRE platform, submit FOB Destination pricing inclusive of freight, and comply with Net 30 payment terms and triplicate invoice submission to APInvoices@dart.org. No set-aside restrictions or disadvantaged enterprise participation goals appear in the recent postings.

Recent activity concentrates in Texas, specifically DART in Dallas County, and California (Riverside County). DART posted four fastener procurements between January 21 and January 29, 2026, with response deadlines between January 28 and February 5, 2026; these included 1/4-28 zinc elastic stop nuts (solicitation 2097736, due February 5, 2026), M8 ESNA hex stainless steel suspension springs (solicitation 2097609, due January 28, 2026), and 9/16"-18 Grade 8 nuts (solicitation 2097554, due January 28, 2026). Riverside County's RFB3909 for Cla-Val parts inventory closed February 13, 2026. One outlier—the City of Lavonia, Georgia water treatment plant construction project (PE66940NONST2026000000005, sealed bid due May 26, 2026)—is tagged to this code but involves comprehensive infrastructure upgrades with no clear connection to nutplate procurement; it reflects misclassification rather than relevant activity under the code.
