Self tapping screws are versatile fasteners widely used across wood, metal and plastic assembly. They form mating threads inside pre-drilled pilot holes without pre-made internal threads.
Different thread profiles and point styles match different materials. Sharp wood self tapping screw has wide spaced threads for timber. Fine thread self tapping screws are designed for thin metal sheet and plastic parts.
Common surface finishes include zinc plating, black oxide and stainless steel. When selecting self tapping screws, confirm pilot hole diameter, substrate thickness and required pull-out strength. They are widely used in furniture, electrical cabinet and general assembly industry.
