Automotive light maker Varroc Lighting Systems will soon begin using additive manufacturing for plastic production parts fastened into assemblies. Here are the results of its tests with self-tapping screws. Peter Zelinski.

Abstract - The tapping screw is a well-developed, widely used fastener. The manufacturing processes of tapping screws are sequentially wire-manufacturing, forming heading and threading , carburizing heat treatment, and phosphate coating, which can be conducted by subcontract factories. The performance qualities of tapping screws are affected by the manufacturing qualities of subcontract factories. In this study, to improve the quality of AISI low carbon steel tapping screws, Taguchi method is used to evaluate the manufacturing qualities of subcontract factories. The quality characteristics of tapping screws, such as case hardness, core hardness, torsional strength, and drilling time, are investigated, and so are their process capabilities.

A self-tapping screw is a screw that can tap its own hole as it is driven into the material. Self-tapping screws have a wide range of tip and thread patterns, and are available with almost any possible screw head design. Common features are the screw thread covering the whole length of the screw from tip to head and a pronounced thread hard enough for the intended substrate , often case-hardened. For hard substrates such as metal or hard plastics, the self-tapping ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap. Thus, whereas a regular machine screw cannot tap its own hole in a metal substrate, a self-tapping one can within reasonable limits of substrate hardness and depth. For softer substrates such as wood or soft plastics, the self-tapping ability can come simply from a tip that tapers to a gimlet point in which no flute is needed. Not all self-tapping screws have a sharp tip. The type B tip is blunt and intended for use with a pilot hole , often in sheet materials. The lack of a sharp tip is helpful for packaging and handling and in some applications may be helpful for reducing the clearance necessary on the reverse of a fastened panel or for making more thread available on a given length screw.
