Use them as general purpose fasteners for almost any fastening purpose in harder metals such as steel, special alloy steels and cast iron. Utilizing a standard machine screw thread, they perform their thread cutting function in metals of any thickness and may be used over and over. Because these screws possess almost twice the strength of ordinary machine screws much smaller screws can be used. When driven into untapped holes (drilled or punched) they stay snug in their self-cut, perfectly mated threads. Type 1 thread-cutting screws conform to American National Standard machine screw dimensions and tolerances.
