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 capturing fasteners commonly sourced as consumable supplies in construction and facility maintenance projects executed by state and local public bodies. State and local governments buy self-drilling screws primarily as component materials embedded in broader construction and renovation work — drywall installation, metal framing assembly, roofing repair, and interior finish work — rather than as standalone procurements. The screws are typically requisitioned through general contractors or trade subcontractors as line items within time-and-materials or unit-price contracts that cover painting, drywall, acoustical ceilings, flooring, and related building services. Issuing bodies under this code include county education agencies, school districts, and facility-management cooperative purchasing alliances that aggregate demand across multiple member jurisdictions to achieve volume discounts and simplified procurement administration.

Recent activity shows Harris County Department of Education (HCDE) and its cooperative purchasing partner Choice Partners (CP) soliciting painting, drywall, acoustical ceiling, and flooring services under a Job Order Contracting (JOC) vehicle — Competitive Sealed Proposal 26021MR, due May 15, 2026 — where self-drilling screws function as a catalog-priced supply item available through contractor-submitted unit-price coefficients applied to established BNi and RS Means databases. The HCDE/CP contract carries a maximum annual aggregate price of $200 million across all awards, with an initial one-year term and up to three automatic one-year renewals. Texas dominates the recent visible activity; no other states appear in the current opportunity block. The market remains sparse at the commodity level, suggesting that self-drilling screws typically flow through larger construction and maintenance RFPs rather than standalone fastener solicitations.
