    1. Descriptions:

     

          A self-tapping screw is a type of screw that taps and threads its own hole as it is installed. Different tapping styles are used with different materials. For example, self-tapping screws for metal utilize a gap in the continuity of the thread, which generates a flute and a cutting edge similar to those on a standard tap; self-tapping screws for wood or soft plastics often use a tip that tapers to a gimlet point, which forms a tap hole by displacing the surrounding material. Also known as self-drilling screws.

     

         Self tapping screws including:

    • Type A self-tapping screws feature coarse threads and are commonly used in wood or thin metal materials from 0.015” to 0.05” thick.
    • Type AB self-tapping screws feature fine threads, and are more effective for brittle materials.
    • Type B self-tapping screws have blunt tips and are often used with plastics or thin metals from 0.05” to 0.2” thick.

         High-Low self-tapping screws  have double lead threads where one thread is high and the other low, which provide easier penetration into the substrate. The high threads are sharper than conventional threads, which causes less displacement of material as the screw is driven in; consequently, less effort is required to drive in High-Low self-tapping screws. The low threads, which run between the high threads, increase the screws’ contact with the substrate material for a stronger grip and increased resistance to pullout and vibrational loosening.
