UNSPSC 31161712: Flange nuts

UNSPSC 31161712 Flange nuts, a Commodity code, covers the supply of fastening hardware—primarily nuts in various grades, sizes, and materials—that state and local governments procure as consumable inventory and component parts for operational and maintenance activities. The recent opportunities under this code show transit authorities and municipal utilities sourcing nuts through straightforward goods procurements, typically for fleet maintenance, water treatment infrastructure, and general operational repair and replacement needs. The Dallas Area Rapid Transit Authority (DART) is the dominant issuing body in recent activity, posting multiple purchase orders for fasteners including 1/4-28 elastic stop nuts, M8 hex fasteners with suspension springs, and Grade 8 nuts in 9/16"-18 size across January and February 2026. Procurement volumes are small—packages and boxes of 25 to 100 units—indicating recurring consumable replacement rather than one-time construction purchases. These are low-dollar, routine supply buys with tight turnaround times (typically one to two weeks from posting to bid deadline) and standardized terms requiring FOB Destination pricing, Net 30 payment, and compliance with standard vendor certifications.

Recent opportunities concentrate in Texas and California. DART in Dallas County, Texas posted four separate nut and fastener purchases between January 21 and January 29, 2026, all with response windows of seven to nine days and delivered through the BONFIRE procurement platform. Riverside County, California issued a Request for Bid (RFB 3909) on January 21, 2026, for miscellaneous Cla-Val parts inventory with a February 13, 2026 deadline. The City of Lavonia, Georgia, operating under Fayette County jurisdiction, posted a water treatment facility improvement project (PE66940NONST2026000000005) with a May 26, 2026 sealed bid deadline that encompasses construction work including modifications to multiple plant systems—work that would incidentally involve fastener procurement but does not represent the typical commodity-level flange nut sourcing captured by this code. The actual flange nut procurement activity is concentrated among transit authorities and utilities buying in small, routine quantities; no set-asides or enterprise preferences are stated in recent DART or Riverside County opportunities.
