- Application: Taps and dies are metal threading tools used to cut and restore internal and external threads precisely. A tap is used to form the female component of the assembly, as in the case of a nut or socket, a die is used on the male component, as in a screw or bolt. In other words, a Tap is used to create the internal threads in a hole for use with a threaded fastener and a die is used to make or repair external threading on a round rod, screw, or bolt.
- Thread Pitch Gauge: Thread pitch gauges are used as a reference tool in determining the pitch of a thread that is on a screw or in a tapped hole. This tool is not used as a precision measuring instrument, rather it allows the user to determine the profile of the given thread and quickly categorize the thread by shape and pitch.
