Rethreading Dies

External Thread Tools in UNC and UNF Sizes

Tap and Die sets are 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 Tap is used for the internal threads. Tools like a T handle wrench are used with a tap to create or repair an internal thread. A die is used on a blank or damaged rod to create or repair the threading of the fastener. Essentially, a die is used to create the threading of a bolt. Dies are available in UNC (Coarse Thread) and UNF (Fine Thread) varieties.

All Dies feature Thread Reliefs to provide easier cutting action and reduce friction by helping to remove shavings from the rethreading. The number of reliefs varies on the size of the Die.

Hex Rethreading Dies

Hex Rethreading Dies are used to restore bruised (rounded) or rusty threads on screws and bolts. Rethreading Dies are hexagonal in shape and may be turned with a wrench. Hexagonal Rethreading Dies are the same size as their respective standard hex nut sizes.
