UNSPSC 31161523: Wing screw

Steels screws easy to recognize because of the flat wing head, with that head we can screw with hands, this screw is in accordance with the DIN 316 standard.

UNSPSC 31161523 Wing screw is a Commodity code that does not appear to map to the state and local procurement activity currently tagged under it. The Harris County Department of Education (HCDE) and Choice Partners cooperative purchasing vehicle posted a Competitive Sealed Proposal on May 15, 2026 for Painting, Drywall, Acoustical Ceilings, and Flooring services — a maintenance and job order contracting (JOC) opportunity that bears no relationship to wing screws or fastener procurement. The code shows little relevant recent activity in state and local solicitations; the single tagged opportunity reflects a classification mismatch rather than genuine demand for the commodity under this code.

When pursuing fastener-related work through state and local procurement channels, business development professionals should verify the UNSPSC coding independently in solicitation documents, as the tagging in aggregate opportunity databases does not always reflect the actual goods or services being solicited. The HCDE/Choice Partners JOC contract, which carries a maximum annual aggregate price of $200 million and runs for an initial one-year term with up to three automatic one-year renewal periods, may include wing screws as subordinate materials within the broader painting and flooring scope — but the opportunity itself targets general contractors and service providers in those trades, not fastener suppliers.
