UNSPSC 31161702: Bearing nuts

UNSPSC 31161702 Bearing nuts is a Commodity code covering the procurement of fastening hardware components for operational and maintenance support across state and local transit, utility, and municipal infrastructure. State and local governments procuring under this code are actively buying elastic stop nuts, Grade 8 hex nuts, and specialty fasteners in standard unit packages (boxes of 25, packages of 100) for transit fleet maintenance, water treatment plant upgrades, and field operations. The Dallas Area Rapid Transit Authority has posted multiple bid solicitations for bearing nuts and related fasteners (elastic stop 1/4-28 zinc-plated nuts, M8 ESNA hex fasteners with suspension springs, and 9/16"-18 Grade 8 nuts) between January and February 2026, indicating ongoing consumable demand for transportation systems maintenance. Issuing bodies under this code include transit authorities and municipal utilities; DART dominates recent activity with four separate fastener-related solicitations in the source period.

Recent activity concentrates in Texas and California, with DART (Dallas County) posting the bulk of fastener opportunities at multiple spec levels in late January and early February 2026, all with 7-day response windows and FOB Destination shipping requirements, payment terms Net 30, and invoice submission via BONFIRE platform. DART's procurement pattern shows no set-aside designations and strict delivery-schedule enforcement with termination-for-default clauses. Riverside County, California issued an RFB for Cla-Val parts inventory on January 21, 2026 (due February 13), representing utilities-sector demand. The City of Lavonia, Georgia (Fayette County jurisdiction) posted a sealed-bid water treatment plant construction project (posted April 24, 2026, due May 26, 2026) that includes modifications to pump stations and filtration systems but does not represent direct bearing-nut procurement; this opportunity is tangential to the code's primary commodity scope and may reflect miscoding. DART's dominant position and rapid-cycle procurement frequency signal active, price-sensitive consumable buying with short lead times and compliance focus on delivery timelines and commercial warranty standards.
