Rainbow World is the manufacturer and exporter of Self Tapping Screws. Rainbow World offers a wide range of precision engineered CNC machined components, turned components, stainless steel fasteners, alloy steel fasteners, etc. The Self Tapping Screws are extensively used with sheet metal and plastic components. Sometimes the ability is created by bearing the gap in the continuity of the thread on the screw. The edges can be cut their own threads as the screw passes in to the material, which is of wood or plastic. The range of self tapping screws also exists for metal. These self tapping screws function by having a cutting edge that drills away the material, putting a hole for the screw to go through. Self tapping screws are widely used when doing metal and wood work.
