UNSPSC 31161800: Washers

UNSPSC 31161800 Washers is a Class code covering fastener components—primarily metal washers, bolts, nuts, and related hardware—that state and local governments procure as materials for maintenance, construction, and infrastructure repair. Recent state and local solicitations under this code show activity concentrated in metals supply for public works inventory, transit system maintenance, and infrastructure projects, with issuers including county public works departments, regional transit authorities, and state transportation agencies. The Orange County (California) Public Works IFB for Various Metals and Related Hardware (IFB0803113903DS, due November 4, 2026) exemplifies the scope: a $855,000 three-year contract covering 34 line items of steel, aluminum, stainless steel, and galvanized materials including pipes, tubing, bars, sheet metal, and miscellaneous fastening supplies, with the contractor maintaining inventory within a 30-mile radius and delivering within ten working days of order. The Dallas Area Rapid Transit Authority (DART) Purchase Order 2100828 (due September 11, 2026) solicited bolts (1/2"-13 X 2-3/4") on net 30 terms with FOB Destination freight included. The California Department of General Services Procurement Division posted an RFI for main line guardrails (RFI 0000040068, due September 14, 2026) that includes bolts, washers, plates, nuts, and metal sleeves as component materials for a statewide two-year contract anticipated at $5 million annual value available to Caltrans and other state agencies.

Recent activity centers in California and Texas, with additional procurement from Georgia and Pennsylvania. Orange County Public Works and the state of California are repeat issuers under this code family. The issuing-body mix reflects operational maintenance across public works departments, special districts (transit authorities), and state procurement offices. Geographic spread spans the West Coast (California, particularly Orange County) and the South (Texas, Georgia), with municipal activity in the Mid-Atlantic (Pittsburgh, Pennsylvania). The code shows consistent demand for fastener inventory replenishment and materials-supply contracting, driven by infrastructure maintenance cycles and capital projects requiring bulk materials supply with guaranteed pricing, delivery windows, and multi-year terms. Local small business and disabled veteran business enterprise preferences appear in several recent solicitations, signaling competitive pressure on pricing and operational capacity requirements.
