Taps and Dies

Taps and dies are cutting tools used to cut screw threads on mating components, which is called threading A threading tap is used to cut the female thread for example in a nut and a threading die is used to cut the male thread for example on a bolt The cutting of threads using a tap is called tapping and the process using a die is called threading. Both tools can be used to create new and clean up existing damaged threads Dies are usually used in a die stock by hand but can also be used on a machine for example a centre lathe Taps are available as hand taps or machine taps.

Thread Plug Gauges

Go / No-Go plug and ring gauges are used as a quality check for the inspection of plain or threaded mating components The gauge is used to check the machined components against its specified drawing tolerances The specified gauge is used to check to ensure interchangeably of and the performance of manufactured parts The Go / No-Go gauge is a tool that does not return a size but instead returns a state of condition. Which is either acceptable and the part is within its specified tolerance or it is unacceptable and would be rejected.
