Self-tapping screws are a popular type of industrial fastener Malaysia. Self-tapping screws were one of the first designed fastener products, made of hardened steel, and its adoption ignited the industrial revolution. A self-tapping screw can be appropriately defined as a tapping screw, but it is also commonly referred to as a sheet metal screw due to its widespread use in the sheet metal sector. A self-tapping screw, by whatever name it is known, is so named because it has formed mating threads in a pre-drilled hole into which it is pushed. A self-drilling screw, on the other hand, is a sort of self-tapping screw that also has a drill tip. In a single action, the sharp drill tip will drill a hole and produce the mating threads.
