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 that covers specialized chain products in varying grades, sizes, and materials—transport-grade steel chain, alloy steel grade 100 chain, galvanized proof coil chain, and zinc chain—sourced by state and local governments for operational inventory, equipment maintenance, and securing applications across multiple municipal departments. State and local issuing bodies soliciting under this code include cities (particularly Tampa, Florida) and counties (Hillsborough County), which procure chain as part of broader lifting, securing, and operational-support inventories alongside related hardware such as shackles, hooks, and slings. The City of Tampa Purchasing Department appears as a repeat buyer, issuing separate RFQs for chain inventory and for hooks and shackles within a three-month window in 2026, suggesting regular cyclical procurement across municipal divisions.

Recent activity clusters in Florida, with the City of Tampa and Hillsborough County issuing RFQ 26-P-00328 for chain inventory (posted May 12, 2026, due June 15, 2026) covering six line items of specialized chain ranging from 3/16 inch to 3/8 inch diameter in grades 30 and 100 with FOB Destination delivery within five business days, and RFQ 26-P-00214 for hooks and shackles (posted March 18, 2026, due April 15, 2026) that included 316 stainless steel chain and roller chain components among 20 total line items. Sourcewell, a Minnesota-based cooperative purchasing vehicle, also issued an RFP for law enforcement equipment (RFP #061626, due June 16, 2026) that spans multiple Washington counties and public entities nationwide, though the available documentation does not specify whether chain products fall within that solicitation's scope. Both Tampa RFQs require electronic submission through OpenGov, firm fixed pricing with shipping included, and compliance with Florida's E-Verify and public records requirements, with payment terms at approximately 30 days post-delivery.
