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 state and local governments procure as a component material within broader maintenance and repair service contracts rather than as a standalone product. The recent solicitation activity under this code reflects how wing screws and similar fasteners are embedded in the scope of commercial trades and facility maintenance work across municipal and educational facilities. State and local issuing bodies soliciting under this code include cities and county educational cooperatives that consolidate procurement across multiple member districts. The City of Lubbock and the Harris County Department of Education (HCDE) appear in the most recent postings, each establishing multiple-award contracts for ongoing maintenance and repair services where fastening materials like wing screws are specified components of the work.

The code shows activity concentrated in Texas. The City of Lubbock posted an ITB on September 27, 2026, due October 20, 2026, for commercial trades and repair services on an as-needed basis across city facilities, with no estimated contract value disclosed. The Harris County Department of Education, in partnership with the cooperative purchasing vehicle Choice Partners, issued a Competitive Sealed Proposal (26021MR) posted May 15, 2026, for painting, drywall, acoustical ceilings, and flooring services with an initial one-year term and up to three one-year renewals; this contract encompasses both time-and-materials maintenance work and job-order-contracting components and carries a maximum annual aggregate contract price of $200 million across all awards. Both opportunities structure procurement as indefinite-quantity frameworks, suggesting that wing screws and related fasteners are called out as needed items within broader service delivery rather than as scheduled quantities.
