Thread size refers to the threads per inch (TPI) that the die uses to cut into a workpiece.
Hex size refers to the distance between two adjacent sides of the die. The hex size is also known as the width across flats.
Hex rethreading dies are made from a variety of materials that are chosen according to the degree of precision, hardness, durability and wear resistance required by your application.
Carbon steel is a soft, durable metal. It is commonly used in general purpose applications on abrasive materials and nonferrous materials.
Chromium steel features the principle element of chromium and has a higher heat resistance as compared to High Speed Steel (HSS). It offers good machinability, wear resistance and toughness.
High speed steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
Hex rethreading dies are used for rethreading or reconditioning worn, damaged or rusted external threads in maintenance or repair operations. They can be used with a wrench or a die holder.
