Historically, the threading of holes has been a fairly straightforward operation, usually performed close to the end of a part’s machining. Once the holes had been drilled, thread taps of the ...

Tapping internal threads on stainless steel pipe fittings is highly technical, typically done using a tap. Stainless steel is highly viscous and has poor chip-breaking properties, so it is easy to ...

Tapping screws form mating threads in materials they are driven into. There are two basic types: thread forming and thread cutting. The thread-forming screw displaced material around the pilot hole so ...

The strength of some internal threads is more sensitive to tap diameter than previously thought. • Cold-formed threads are no stronger than cut threads when holes are correctly sized. • Cut threads ...
