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, while 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 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, but rather it allows the user to determine the profile of the given thread and quickly categorize the thread by shape and pitch.

T-Handle Thread Tap Set is a useful tool that provides extra leverage for hand tapping, making it very useful for confined spaces or where extra reach or leverage is required. T-Handle Tap wrenches may also be used with screw extractors, drills, and other tools.

The taps and dies in this set are typically made of high-speed steel or hardened carbon steel, with the former being much more robust and used for a broader range of materials. These cutting materials are suitable for threading steel, cast steel, cast iron, non-ferrous metals, plastics, softwood, and hardwood.
