taptite screws: types,uses and making methods. kindly explain.

 

[CoryPad]

There are a few different types of Taptite (R) threads, but all provide the same function: rolling mating threads during installation. You can get more information from:

The manufacturing method is the exact same as machine screws: cut a blank from wire, forge the head/shank features, roll threads.

A couple additions to CoryPad's manufacturing methods.

Unlike "normal" machine screws, the "pre-threadroll" (as cold headed) shank diameter is not round, but has a cross section that will generate the desired "trilobular" thread shape/dimensions after thread roll. These screws are also typically case hardened.
