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 (Commodity) captures fastening hardware and related components purchased by state and local governments for infrastructure maintenance and capital construction. Recent solicitations show the code applied to both discrete fastening components—such as bolts and washers for transit rolling stock and facilities—and to structural anchorage systems integral to water treatment plant upgrades and similar municipal capital projects. Issuing bodies span transit authorities, municipalities, and water utilities; the Dallas Area Rapid Transit Authority (DART) appears as a repeat buyer of fastening hardware for fleet and facility maintenance.

Activity is concentrated in the South, with recent opportunities posted from Texas (DART) and Georgia (City of Lavonia water treatment facility), though the sparse recent record suggests the code sees limited posting volume. DART solicited 1/2"-13 X 2-3/4" bolts under Purchase Order 2100828 (RFQ, due September 11, 2026), requiring FOB Destination freight terms, Net 30 payment, and triplicate invoice submission to APInvoices@dart.org. The City of Lavonia, Georgia solicited comprehensive water treatment plant improvements (sealed competitive bid, due May 26, 2026) including new flash mixer and mixing basin, settling basin modifications, filtration upgrades, and ancillary structural work—a project where anchor plates and washers are incidental components within broader construction scope. The Lavonia project carried Davis-Bacon prevailing wage requirements, E-Verify work authorization, Georgia Utility Contractor licensing, 4.0% DBE participation goals, and Build America Buy America Act compliance. Few additional opportunities appear under this code in state and local procurement; the category may see more activity under higher-level fastener or structural hardware classes.
