A self-drilling screw, also known as a Tek screw or self-tapping screw, is a type of fastener that combines the functions of drilling and fastening into a single action. Unlike traditional screws that require a pre-drilled hole, self-drilling screws have a drill-like point and special threads that allow them to create their own hole as they are driven into the material.
The self-drilling feature of these screws eliminates the need for a separate drilling step, making them convenient and efficient to use. They are designed to be used with materials such as metal, wood, or plastic, where they can create a threaded hole as they are screwed in. The drill point at the tip of the screw helps to pierce and penetrate the material, while the specially designed threads on the screw shaft facilitate easy insertion and provide a secure fastening.
