Self-Drilling Screws – One-Step Fastening Solution for Metal & Sheet Applications
Product Description
Self-Drilling Screws, commonly referred to as Tek Screws, are precision-engineered fasteners designed to drill their own hole and tap threads in one step, eliminating the need for pre-drilling. These screws come with a drill-like fluted tip (TEK point) that cuts into materials such as steel, aluminum, wood, or composite sheeting.
At SM Fasteners, we manufacture high-performance self-drilling screws with superior coatings and drive types including hex washer head, pan head, truss head, and countersunk head. Available in zinc-plated, Ruspert, Epoxy coated, and stainless steel finishes, they are built to perform in demanding environments like roofing, HVAC, construction, and electrical installations.
Applications
Self-drilling screws are used in a wide range of light to heavy-duty fastening applications where speed and structural integrity are crucial:
Metal-to-Metal & Metal-to-Wood Fastening
Steel Framing and Roofing Sheets
HVAC Duct Installations
Electrical Panel and Junction Box Assembly
Cladding, Façade & Curtain Wall Systems
Cable Trays and Purlins
Solar Panel Structures and Mounts
