The tap and die set consists of two types of complementary tools: a tap, which is used to cut threads into a bolt hole (or nut, to which it is colloquially referred) and a die, which is used to cut threads into a bolt that has been damaged or stripped. Even ordinary pieces of steel rod can be made into a bolt (if you just happen to have some lying around)! These tools are used mainly by mechanics and woodworkers, but can be used for bicycle and small-engine repairs as well.

Usage involves first determining the correct size of the piece from the tap and die set; this will fit into a wrench which will be used to turn the piece. The bolt or bolt hole is then held in place with advise and turned with the wrench in ¼ turn increments until the threads are cut down the bolt or bolt hole. One reverse turn may be required every so often to clean up the threads. Cutting oil can be extremely useful in this process, as it allows the tap or die piece to move more easily.
