The material flows around the threads of the screw, resulting in a zero-clearance fit. This makes them ideally suited for materials where large stresses are needed to resist loosening, such as in steels, stainless steels, light metals, and light metal alloys.
Type A - The point of this self-tapping screw is sharp enough to pierce many metal substrates as thick as 16 gauge. However, for deeper metals, a pre-created hole will be necessary.
This self-tapping screw is perfect for use with a hard material such as metal and hard plastics. The full thread on the screw means that the screw can tap its own hole as it is driven into the material.
A self-tapping screw is a screw that can tap its own hole as it is driven into the material. More narrowly, self-tapping is used only to describe a specific type of thread-cutting screw intended to produce a thread in relatively soft material or sheet materials, excluding wood screws.
