    Description

    Description


    Self-drilling screws, also known as self-tapping screws, are a special fastener. It combines the functions of a drill bit and a screw, and when screwed in is able to drill itself into the material and create threads without the need for pre-drilling or tapping. This makes the installation process faster and easier, especially where quick assembly is required.

    The end of the drill screw has a design similar to a drill bit and has cutting edges to cut into the material. As the screw is rotated into the material, its threaded portion follows this newly formed hole and creates a matching internal thread in it, holding the screw firmly in place. This type of screw is ideal for metal, wood and some other harder materials.


    Sort by head shape

    Countersunk Head

    Suitable for occasions where the screw head is flush with the surface of the material.

    Round Head

    It is usually used for applications where decorative requirements are not high or a certain protruding height is required.

    Hex Head

    Provides better torque transfer for scenarios requiring higher tightening forces.
