Self-tapping fasteners are specially designed screws with the ability to advance when turned while creating its own thread.
They are commonly used with sheet metal and plastic components. This ability is created sometimes by creating a gap in the continuity of the thread on the screw. These edges can cut their own threads as the screw is driven in to the material, usually wood or plastic, as well as for metal. They function by having a cutting edge which drills away the material, making a hole for the screw to go into.
Unisteel’s range of self tapping fasteners include licensed products like Taptite®, Remform® and Delta PT® to select from.
