UNSPSC 31161813: Swivel washers

UNSPSC 31161813 Swivel washers, a Commodity code, encompasses fastener components that state and local governments buy for equipment maintenance, infrastructure repair, and capital projects. Recent solicitations show the code capturing industrial fasteners in transit maintenance, water treatment facility upgrades, and utility infrastructure work. The issuing bodies span transit authorities, municipal governments, and water utility districts, each soliciting individual components or bulk fasteners as part of larger procurement packages. Work under this code ranges from single-item bolt orders to fastener requirements embedded in comprehensive construction projects, where swivel washers and related hardware support assembly, structural integrity, and operational systems.

Dallas Area Rapid Transit Authority (DART) posted a purchase order (Solicitation 2100828) on September 3, 2026, requesting 1/2"-13 X 2-3/4" bolts with a response deadline of September 11, 2026, specifying FOB Destination freight terms and Net 30 payment. The City of Lavonia, Georgia, issued a sealed competitive bid (Solicitation PE66940NONST2026000000005) on April 24, 2026, for Water Treatment Plant 2026 Improvements, with a May 26, 2026, deadline and a May 7 pre-bid conference; the project encompasses facility upgrades requiring fastener components as part of the broader $3.0-million-gallon-per-day treatment capacity expansion, with Davis-Bacon Act prevailing wage requirements and 4.0% DBE participation goals. Recent activity concentrates in Texas and Georgia, with transit and municipal water infrastructure as primary drivers. Response dates and freight terms are contractually material in DART solicitations, and pre-bid conferences are standard where construction scope is substantial.
