UNSPSC 31161530: Grub screw

A type of set screw having no projecting head. Its top is either slotted or provided with a socket.

UNSPSC 31161530 Grub screw is a Commodity code that captures fasteners used in maintenance, repair, and construction work across state and local facilities. Recent solicitations tagged to this code show state and local governments purchasing grub screws as part of broader commercial trades and facility repair contracts rather than as standalone fastener procurements. The City of Lubbock and Harris County Department of Education (HCDE) are among the recent buyers, soliciting grub screws within multi-trade repair and maintenance frameworks. The issuing bodies span municipalities and county education authorities, reflecting the distributed nature of facility maintenance work across local government operations.

Recent activity is concentrated in Texas. The City of Lubbock posted an ITB on September 27, 2026 for Commercial Trades & Repair Services and Commercial Specialty Services on an as-needed basis, with proposals due October 20, 2026, establishing multiple contracts to support operational needs across city facilities; grub screws would be ordered as incidental materials within these broader repair frameworks. The Harris County Department of Education and cooperative purchasing partner Choice Partners issued a Competitive Sealed Proposal on May 15, 2026 for Painting, Drywall, Acoustical Ceilings, and Flooring services with an initial one-year term and up to three automatic one-year renewals, a maximum annual aggregate contract price of $200 million across all awards, and a tentative award date of July 15, 2026. The code shows limited standalone fastener procurement activity; grub screws appear as component materials within larger trades contracts rather than as discrete line items.
