セルフタッピングネジは、ネジが事前に掘削された穴に押し込まれるようにネジ山（タッピングネジ）を形成するネジファスナーのクラスです。プリンスファスナーセルフタッピングネジは、ネジ切り、ネジ転造、セルフドリルねじで構成されています。Our self tapping screws can be personalized to your utility and industry.Self-tapping screws have a large vary of tip and thread patterns, and are reachable with nearly any feasible screw head design.Common facets are the screw thread protecting the entire size of the Prince fastener screw from tip to head and a mentioned thread tough ample for the supposed substrate, frequently case-hardened.For difficult substrates such as metallic or difficult plastics, the Prince fastener self-tapping capacity is frequentlycreated through slicing a hole in the continuity of the thread on the screw, producing a flute and reducing aspect comparable to these on a tap. Thus,whereas a everyday desktop screw can’tfaucet its very own gap in a steel substrate, a self-tapping one can (within practical limits of substrate hardness and depth).For softer substrates such as timber or smooth plastics, the Prince fastener self-tapping potential can come in reality from a tip that tapers to a gimlet factor (in which no flute is needed). Like the tip of a nail or gimlet, such a factor varieties the gap by using displacement of the surrounding fabric as an alternative than any chip-forming drilling/cutting/evacuating action.Not all self-tapping screws have a sharp tip. The kind B tip is blunt and meant for use with a pilot hole, regularly in sheet
materials. The lack of a sharp tip is useful for packaging and managing and in some functions may additionally be useful for decreasing the clearance integral on the reverse of a mounted panel or for making greater thread reachable on a given size Prince fastener screw.
