Flow drill and function

Flow drilling uses a special drill bit to generate heat,
softening the metal and forming it into a bushing for threading.

 

Strength of the combination can be gained by more threads.
For example, with flow drilling on 2 mm thick steel, the thread can be increased to about 5 mm.

No additional nuts are needed.

 

The solution provides both functionality and elegance at the same time,
often used in visible positions of assembled structures.

Alchamn Displays Corp. has M6/M8/M10 optional flow drilling bit to meet customer demands.
