Introduction:

Self drilling screws, also known as Tek screws, are fasteners with a special pointed end style that allows them to penetrate thin materials without a starting or pilot hole. Also known as self tapping screws or self drilling bolts, they cut or form threads to engage with the mating material. When selecting a self drilling screw, consider the type of point required for the application, system of measurement, thread size, material and coating, compatible materials, head style, and drive style. Steel and stainless steel self drilling screws are most common; however, other material types may be available. The fastener may be coated for performance. Self drill bolt types include those designed for wood, concrete, steel, and drywall. They may have a flat head, wafer head, pan head, pan bugle head, or some another less common style. This type of screw may be described as Tek self drilling screws, which refers to the original manufacturer of the design.
