• Unloading step -4 is not required to be made in the event of final agreement
• the groove-forming step 3 is considered as a cut-off, which reduces the direction of breakdowns due to a 4-rupture between the two.
• screw connection is available in the area, which is located in the base of the thread. For example, when screwing the tool into the workpiece, you will need to screw the groove, and by screwing it in, we will make a bad thread.
• the diameter of the pins are in the range between the middle and the open thread model. You may also be able to use it successfully for the restoration of a crumpled thread;
