UNSPSC 31161815: Shoulder washers

UNSPSC 31161815 Shoulder washers, a Commodity code, covers fastener components state and local governments procure for vehicle maintenance, transit systems, and facility operations. Recent solicitations show transit authorities and municipalities buying bolts, fasteners, and related hardware for routine fleet and infrastructure upkeep. The Dallas Area Rapid Transit Authority (DART) represents the primary recent buyer, sourcing bolts and fastening supplies through competitive purchase orders with specific delivery, freight, and payment terms.

Activity under this code is sparse in the current public record. DART's September 2026 solicitation for 1/2"-13 X 2-3/4" bolts (Purchase Order 2100828, due September 11, 2026) is the only recent state or local opportunity explicitly tied to shoulder washers or fastener components; the source shows no other representative purchases under this Commodity code. The second opportunity in the source—the City of Lavonia, Georgia water treatment plant improvements project—is unrelated to fastener procurement and does not reflect activity under this code. Pursuit should focus on transit authorities with fleet maintenance operations and municipalities managing water, wastewater, or transportation infrastructure that requires regular fastener replenishment.
