UNSPSC 31161528: Self drilling screw

Externally-threaded fastener with a self-drilling point that drills, taps and fastens.

UNSPSC 31161528 Self drilling screw is a Commodity code covering fasteners used in construction, maintenance, and facility repair work across state and local jurisdictions. State and local governments procure self-drilling screws primarily as component supplies bundled into broader commercial trades, repair, and maintenance service contracts rather than as standalone fastener purchases. The code sees solicitation activity from municipalities and education-sector cooperative purchasing vehicles managing building maintenance and facility upkeep across multiple properties and service categories.

Recent opportunities show limited direct activity under this specific code. The City of Lubbock issued ITB 2619925SR (due October 20, 2026) for commercial repair, maintenance, and specialty services on an as-needed basis, establishing multiple indefinite-quantity master-service agreements to support operational needs across city facilities, though the notice does not itemize fastener requirements separately. The Harris County Department of Education, procuring through cooperative partner Choice Partners, issued a Competitive Sealed Proposal (26021MR, due May 15, 2026) for Painting, Drywall, Acoustical Ceilings, and Flooring services under a Job Order Contracting model with an initial one-year term and up to three one-year renewals, with a maximum annual aggregate contract price of $200 million across all awards; self-drilling screws would be subsidiary materials supplied by the winning vendors rather than a primary line item. Texas (specifically Harris County and the City of Lubbock) represents the primary geographic concentration in recent postings, though the source provides insufficient depth to characterize broader state-by-state or regional activity.
