The TX-CS-SD range delivers reliable, high-speed fastening into metal substructures without pre-drilling. Featuring hardened steel drill points, these screws are the workhorse of roofing, cladding, and industrial construction across the GCC.
The drill tip simultaneously drills, taps, and clamps — eliminating the need for pre-drilling or pilot holes and significantly reducing installation time on large-scale projects.
