UNSPSC 31161520: Hexagonal head screw

A screw with hexagonal head that follows DIN standard numbers like 931, 933 or 961.

UNSPSC 31161520 Hexagonal head screw is a Commodity code that captures fastener procurement by state and local governments, though recent solicitation activity under this code shows minimal direct relevance to the nominal scope. The recent opportunities posted under this code actually address commercial trades and repair services, painting, drywall, acoustical ceilings, and flooring work — none of which center on hexagonal fasteners as a distinct line item. The mismatch suggests that issuing bodies may be applying this code as a catch-all for maintenance and repair services rather than narrowly to fastener supply, or that individual fastener purchases fall below the solicitation threshold and do not appear in public notices.

The City of Lubbock (Texas) posted an ITB on September 27, 2026 (due October 20, 2026) for Commercial Trades & Repair Services and Commercial Specialty Services on an as-needed basis across City facilities, with intent to establish multiple contracts under a master-service-agreement framework. The Harris County Department of Education (HCDE), in partnership with Choice Partners, issued a Competitive Sealed Proposal (due May 15, 2026) for Painting, Drywall, Acoustical Ceilings, and Flooring services under both a Maintenance Component and a Job Order Contracting (JOC) Component, with a maximum annual aggregate contract price of $200 million across all awards and an initial one-year term with up to three automatic one-year renewals. Neither opportunity targets fastener supply directly. Activity under this code at present shows limited relevant state and local procurement opportunity aligned with hexagonal screw purchases.
