Taps & Dies
Taps and dies serve as cutting tools employed to create screw threads on mating components, a process known as threading. A threading tap is utilised to cut the female thread, found, for instance, in a nut, while a threading die is employed to cut the male thread, as seen in a bolt. The creation of threads using a tap is referred to as tapping, and when a die is used, the process is termed threading. Both tools are versatile, capable of generating new threads or restoring damaged ones. Dies are typically employed manually in a die stock but can also be used with machines like a centre lathe. Taps are available in both hand tap and machine tap variations.

Thread Plug Gauges
Go/No-Go plug and ring gauges serve as a quality assessment tool for examining plain or threaded mating components. These gauges are employed to verify machined components against specified drawing tolerances, ensuring interchangeability and the performance of manufactured parts. The Go/No-Go gauge operates as a tool that doesn't provide a size but rather indicates a condition, classifying the part as either acceptable within its specified tolerance or unacceptable, leading to rejection.
