UNSPSC 31161807: Flat washers

UNSPSC 31161807 Flat washers is a Commodity code representing fastening hardware and components that state and local governments procure for maintenance, repair, and capital construction projects. The code encompasses washers and related fastening elements used in equipment assembly, infrastructure repair, and facility maintenance across transit systems, water utilities, and public works departments. Recent solicitations show state and local buyers purchasing these items both as standalone hardware components and as elements of larger capital projects, with usage patterns reflecting routine operational procurement (replacement parts, maintenance stock) and project-specific requirements tied to facility upgrades and equipment overhauls.

Issuing bodies under this code include transit authorities and municipal utilities. The Dallas Area Rapid Transit Authority (DART) posted a purchase order on September 3, 2026 (bid due September 11, 2026) for bolts under PO 2100828, with FOB Destination shipping and Net 30 payment terms enforced through BONFIRE registration and a triplicate invoice process. The City of Lavonia, Georgia posted a sealed competitive bid on April 24, 2026 (due May 26, 2026) for Water Treatment Plant 2026 Improvements, a comprehensive nine-month upgrade project including modifications to filtration units, chemical feed systems, and clearwell storage tanks—work that would incorporate fastening hardware as a component of the broader construction scope. Geographic activity centers on Texas (DART) and Georgia (Lavonia), with little visible recent activity across other states in the provided opportunities. The Texas and Georgia solicitations reflect the code's dual role: routine procurement of fastening components for fleet and facility maintenance by transit systems, and embedded hardware sourcing within larger municipal infrastructure projects funded through state revolving funds and subject to prevailing wage and BABA compliance requirements.
