UNSPSC 31151610: Hollow pin chain

A serial chain used in industrial machines to be inserted in the sprockets, the hollow pin is at the center of articulation, and always keeps the pitch length.

UNSPSC 31151610 Hollow pin chain is a Commodity code under which state and local governments procure specialized chain products for operational inventory and equipment applications. The scope of work encompasses various grades and sizes of industrial chain — including transport grade, alloy steel, proof coil, and galvanized variants — sized from 3/16 inch to 3/8 inch diameter and sold in quantities ranging from 100 to 800 feet. State and local buyers include city purchasing departments acting on behalf of multiple municipal divisions, county governments, and cooperative purchasing vehicles serving multi-jurisdictional public entities. The work itself is straightforward commodity procurement with technical specifications driven by end-use requirements across public operations.

Recent activity shows two contracting approaches. The City of Tampa Purchasing Department issued RFQ 26P00328 in May 2026, seeking six line items of specialized chain products (posted May 12, 2026; due June 15, 2026) to support various Hillsborough County and City of Tampa departments, with one-year contract terms, FOB destination delivery within five business days, and payment at approximately 30 days. Separately, Sourcewell — a Minnesota local government unit and cooperative — posted RFP 061626 in May 2026 (due June 16, 2026) for law enforcement equipment on behalf of participating entities across Washington state and multiple U.S. jurisdictions; however, the law enforcement equipment solicitation appears unrelated to hollow pin chain despite the code assignment. Geographic activity centers on Florida (Tampa-Hillsborough County) and Washington state (multi-county cooperative), with the Tampa procurement representing direct municipal demand. No set-aside designations, incumbent contractors, or budget ranges are disclosed in available documentation.
