Self Drilling Screws (SDS), also known as Tek Screws, are high-performance fasteners engineered with a drill bit tip that allows direct penetration into metal or wood without the need for pre-drilling. Made from premium-grade steel and available with zinc or stainless steel finish, these screws ensure excellent corrosion resistance and long-lasting durability. Ideal for roofing, cladding, fabrication, and construction applications, SDS screws provide strong holding power and precise fastening, reducing installation time and improving efficiency. Available in various head types (Hex, Pan, or CSK) and drive styles (Phillips, Slotted, or Hex), they deliver consistent performance in both light and heavy-duty applications.
