UNSPSC 31161834: Cup washer

A type of washer designed to protect the head of a metal screw from electrical contact.

UNSPSC 31161834 Cup washer is a Commodity code that state and local governments use to tag fastener and hardware components — though recent solicitations show minimal activity specifically under this code. The Dallas Area Rapid Transit Authority (DART) posted a purchase order in September 2026 for bolts (1/2"-13 X 2-3/4") tagged to this code, a mismatch suggesting catalog classification error rather than intentional cup-washer procurement. The second recent opportunity, a City of Lavonia, Georgia water treatment plant improvement project (sealed competitive bid, May 26, 2026 deadline), is a large infrastructure construction effort also tagged to the code but with no evident connection to cup washers or fastener components. The code shows little relevant recent activity and does not appear to reflect what state and local purchasing offices are actively buying under this classification.

The geographic spread across the recent records spans Texas and Georgia, though the sparse activity and classification mismatches limit strategic significance for business development purposes. No state or local issuing body shows repeat procurement activity under this code. The mismatch between the code's nominal scope and the actual work being solicited — bolts and water treatment construction — suggests either data-entry errors in the tagging process or a low-activity code that does not reflect a genuine market segment in state and local procurement.
