You need to cut into the rod thread. Dice you have, but no holder. How to be? Very simple. Choose a nut, which enters the die is tight, with no gap. Saw the thread and nut groove, align it with the similar groove of the die and hammered into the hole the pin slightly asclepia it. The thus obtained holder attach to a corresponding wrench, the workpiece clamp in a vise. Further operations are no different from the usual.
