Thread Pitch (mm)
* All information without guarantee.
1. Determine the pin diameter with a caliper gauge.
2. A tropical cutting oil on the tap and on the bolt.
3. Then turn the tap one turn clockwise.
Attention! Always place the die straight and not at an angle!
4. Then turn the tap counterclockwise for half a turn.
This is very important in order to break off the chip that occurs during cutting.
5. Repeat the cutting process as described in points 3. and 4. until the desired thread length has been reached.
The function of the finished thread can then be checked with a suitable nut.
