UNSPSC 31161817: Conical washers

UNSPSC 31161817 Conical washers, a Commodity code, does not align with the recent state and local procurement activity tagged under it. The two recent opportunities on file — a Dallas Area Rapid Transit Authority purchase order for 1/2"-13 X 2-3/4" bolts (not washers) and a City of Lavonia water treatment plant construction services RFB — fall outside the fastener hardware scope the code nominally covers. The bolt solicitation is a straightforward parts procurement, while the water treatment facility work is civil construction requiring site preparation, equipment installation, and system integration. Neither opportunity involves conical washers or the component-level fastener hardware the code name denotes.

The mismatch between code and work suggests that state and local procurement systems occasionally misclassify fastener and component purchases, or that conical washers do not appear frequently enough in recent state and local RFPs to generate representative activity. If conical washers are being procured by state or local bodies, they are either tagged under different codes or posted through cooperative purchasing vehicles and private-sector catalogs that do not surface in public solicitation databases. A firm evaluating pursuit under this code should assume little recent visible demand and verify actual buying patterns through direct outreach to transit authorities, water utilities, and maintenance departments that typically stock such components.
