Type 23 Thread Cutting Screws for Castings - Fine Thread

TYPE 23 These specially designed self-threading screws are for use in zinc, aluminum and other soft metal die castings. Employing a wider thread-cutting slot, they allow ample clearance for chips. And, the off-center slot presents an acute angle, with sharp cutting edges for best cutting performance. Type 23 screws are often used in plastics where a standard machine screw thread is desired. They can also be used in harder metals where the advantages of a wide cutting slot are important; or use them for assembly of electrical components of copper or bronze. Made of heat treated, hardened steel,Type 23 screws are available in other materials such as stainless steel, Monel, brass or aluminum on special order.
