Tapping Screw
TAP-004
The hardness and thickness of the substrate used must be within reasonable specifications. Especially for soft materials such as wood or plastic, there is no need to pre-drill holes. Through the screw rotation in a clockwise direction, the tip is under the base plate, and the screw is brought into the plate through the forced cutting and pulling force of each layer of sharp threads, so that the plate is drilled out of holes. Therefore, ordinary screws need to tap holes in the substrate before used, but self-tapping screws can be tapped without pre-drilling holes.
