UNSPSC 31161836: Anchor plate washer

A type of washer with a large plate connected to a tie rod or bolt.

UNSPSC 31161836 Anchor plate washer is a Commodity code that captures industrial fastening hardware — specifically lock washers and related steel plate components — procured by state and local transportation and water infrastructure operators. State and local governments buy these items both as discrete replacement stock for maintenance and repair and as components bundled into larger construction or renovation projects. Issuing bodies are primarily transit authorities and municipal water utilities; the Dallas Area Rapid Transit Authority (DART) and City of Lavonia, Georgia represent the two most recent solicitors.

Recent activity spans Georgia and Texas. DART issued a purchase order on January 21, 2026 (due January 28, 2026) for Washer Lock 7/16" Medium in quantity packages of 100 units as a direct goods procurement through its BONFIRE bidding system, with Net 30 payment terms and FOB Destination freight. The City of Lavonia, operating under Fayette County jurisdiction, issued a sealed competitive bid (solicitation PE66940NONST2026000000005, due May 26, 2026) for the Water Treatment Plant 2026 Improvements project, a comprehensive facility upgrade spanning two sites with a nine-month construction schedule; while the Lavonia solicitation is structured as a construction services bid, anchor plate washers and fastening hardware are embedded components within the broader water treatment facility modifications including new flash mixer installations, settling basin renovations, and filtration system upgrades. Both opportunities require compliance with standard commercial terms including delivery performance guarantees and federal work authorization or tax compliance verification.
