Our BOLTMAKER DIES are given special attention during all manufacturing processes to assure minimum die adjustment is required for diameter, match or taper during setup. This results in an even pressure on the bolt shank during starting and rolling. Add to this the care we exercise in our heat treating operation and you have a true and accurate boitmaker die.
A major cause for boitmaker thread rolling problems is the use of the wrong type of die. In order to successfully roll high quality bolt threads, the dies must be made to the specifications of the machine manufacturer.
