Schr. D7500-C PZ M4x10 EVZ zelfdraadvormende bolkop schroef

DIN 7500 thread forming screws form their own "female thread" in ready-made holes by thread-rolling into malleable material.
The resulting thread corresponds to standard metric thread.

Advantages:
- thread-cutting becomes unnecessary
- no play in the mating threads
- high vibration resistance
- no chips
