Self Drilling

Self-drilling screws, commonly known as “Tek screws,” feature a drill bit-like tip with helical threads that allow them to create both their own hole and thread in various thicknesses of steel, depending on the length of the tip. Most self-drilling screws are suitable for use with materials ranging from 3mm to 5mm thick, depending on the quality and grade of the material. Primarily used for fastening into steel through a variety of materials, they are ideal for applications where speed is essential or where access is limited to one side.
