UNSPSC 31161809: Reducing washers

UNSPSC 31161809 Reducing washers (Commodity) covers metal fastening components purchased by state and local governments for equipment assembly, maintenance, and infrastructure projects. Recent state and local solicitations show the code acquiring lock washers and related hardware components for operational and capital maintenance across water utilities and transit authorities. The work involves direct procurement of industrial fasteners—typically specified by size, material grade, and quantity per package—for use in equipment assembly, facility upgrades, and rolling stock maintenance rather than manufacturing or distribution services.

Activity under this Commodity code spans transit authorities and municipal utilities. The Dallas Area Rapid Transit Authority (DART) posted an IFB on January 21, 2026 for Washer Lock 7/16" Medium (Package of 100) with a response deadline of January 28, 2026, requiring FOB Destination pricing and compliance with DART's standard purchase order terms including Net 30 payment and delivery schedule performance. The City of Lavonia, Georgia, which is operating under Fayette County jurisdiction, posted a sealed competitive bid (PE66940NONST2026000000005) on April 24, 2026 for Water Treatment Plant 2026 Improvements with a May 26, 2026 deadline—a nine-month capital project to increase treatment capacity to 3.0 million gallons per day that would incorporate fastening hardware throughout the facility modifications. Geographic activity concentrates in Georgia and Texas, with procurement driven by transit system maintenance and municipal water infrastructure upgrade cycles. Bidders should note that transit and utility solicitations under this code typically require FOB Destination terms, timely delivery compliance, and formal invoice submission processes, with no apparent set-aside or preference designations in recent postings.
