Hex Rethreading Dies
External Threading Tools in UNC and UNF Sizes
Tap and Die sets are used to cut and restore internal and external threads precisely. 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.
Hex 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 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. High Speed Steels are high-performance special steels offering high hardness at temperatures up to 500°C and high wear resistance, thanks to alloying elements. As such High speed steel does not lose its temper (hardness) with higher temperatures permitting it to cut faster than high carbon steel, thus the name.
