Head Design: CSK head Tek screws feature a flat or slightly tapered head with an angled underside that fits into a countersunk hole in the material being fastened. When installed, the head sits flush with the surface of the material, providing a smooth and streamlined appearance.
Thread Design: CSK head Tek screws have self-drilling points and sharp threads designed to cut through metal surfaces without the need for pre-drilling pilot holes. The threads are typically coarse and provide excellent grip and holding power in metal substrates.
Material and Coating: CSK head Tek screws are commonly made from hardened steel, stainless steel, or other corrosion-resistant alloys to ensure durability and longevity, especially in outdoor or corrosive environments. They may also be coated with zinc, zinc-nickel, or other protective coatings to enhance corrosion resistance and provide additional lubrication during installation.
Size and Length: CSK head Tek screws come in various sizes and lengths to accommodate different material thicknesses and installation requirements. The most common lengths range from 1/2 inch to 3 inches or more, with longer screws used for thicker materials or when attaching to thicker structural members.
Applications: CSK head Tek screws are widely used in construction, roofing, cladding, HVAC, and metalworking applications where a flush and smooth finish is desired. They are suitable for attaching metal roofing panels, wall cladding, gutters, flashing, and other components to steel or aluminum frames.
Installation: To install a CSK head Tek screw, drill a countersunk hole into the material surface to accommodate the head of the screw. Align the screw with the countersunk hole and apply downward pressure while driving the screw using a power drill or screwdriver. The self-drilling point will penetrate the material surface, and the sharp threads will securely fasten the material in place.
