Self-tapping screw

Self-tapping screw

Self-tapping is the ability of a screw to advance when turned, while creating its own thread. Self-tapping screws are commonly used with sheet metal and plastic components. This ability is created sometimes by having 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. Self tapping screws also exist for metal. They function by having a cutting edge which drills away the material, making a hole for the screw to go into.

Self tapping screws are most useful when doing metal and wood work.
