UNSPSC 31161811: Spring washers

UNSPSC 31161811 Spring washers, a Commodity code, encompasses fasteners and related hardware components that state and local governments procure for maintenance, repair, and construction activities. The recent solicitation record shows transit authorities and municipal utilities buying bolts, fasteners, and associated small parts for fleet maintenance and facility upgrades rather than spring washers specifically, indicating the code captures a broader family of fastening hardware than its nominal name suggests. Issuing bodies under this code include regional transit authorities (Dallas Area Rapid Transit Authority) and municipal utility departments, each managing substantial recurring procurement for maintenance materials and capital project support. The work involves supplying standard fastening components to meet ongoing operational needs as well as project-specific requirements tied to larger infrastructure upgrades.

Recent activity appears limited in the public record. The Dallas Area Rapid Transit Authority issued an IFB for bolts (1/2"-13 X 2-3/4") with a September 11, 2026 response deadline, requiring FOB Destination freight terms, Net 30 payment, and registration in BONFIRE to access bid details and submission fields. A second opportunity posted by the City of Lavonia, Georgia in April 2026 for water treatment plant improvements (response deadline May 26, 2026) included associated fastening and hardware materials as subordinate line items within a broader sealed-bid construction project. The code shows minimal recent standalone procurement activity; most fastener requisitions appear embedded in larger maintenance or construction RFQs and ITBs. Geographic activity is concentrated in the South (Texas, Georgia), though this reflects the limited posting record rather than broader regional distribution. Bidders should expect Net 30 payment terms and stringent delivery requirements, particularly from transit authorities where schedule reliability is contractually essential.
