UNSPSC 31161831: Finger spring washer

A type of washer designed to reduce noise and vibration and to prevent excess wear especially at high speeds.

UNSPSC 31161831 Finger spring washer, a Commodity code, covers fastener components and related hardware items that state and local governments procure for maintenance, repair, and construction projects. The recent solicitations under this code, however, show a mismatch between the nominal scope and actual buying activity. The Dallas Area Rapid Transit Authority (DART) solicitation 2100828, posted September 3, 2026, with bids due September 11, 2026, requests bolts (1/2"-13 X 2-3/4") rather than finger spring washers, and the City of Lavonia water treatment plant improvement project covers comprehensive facility upgrades including concrete work, mechanical systems, and chemical feed infrastructure—none of which align with the code's fastener-component scope. The code shows little relevant recent activity under its stated commodity definition. Issuing bodies pursuing fastener and hardware procurement typically include transit authorities, municipalities, and water utilities executing capital maintenance and facility improvement programs, though the opportunities posted under this particular code do not reflect that pattern.

The geographic spread of recent opportunities under this code is limited and does not support a meaningful market characterization. DART operates in the Dallas, Texas region, and the City of Lavonia procurement involves Fayette County, Georgia; however, neither solicitation is substantively aligned with finger spring washer procurement. The code's actual use in state and local procurement remains unclear from the available recent-opportunities data, and no representative fastener-component solicitations are present to establish geographic patterns or issuing-body concentration. A business development professional evaluating this code should verify whether procurement systems are mistagging hardware and fastener items, or whether finger spring washers see activity under different UNSPSC classifications in state and local buying patterns.
