[Mgs] cool tool find

[Hans Duinhoven]

Agree with this strategy of better using a new one.

What I learned of steel behaviour after cold de-forming and reforming again 
at thechnical colege, that this is cold manipulation of the material. This 
will cause the threads become brittle.
IOW the material properties of the screw are absolutely not the same anymore 
as the original bold or screw carried.
This means such a bold or screw cannot predictibly be loaded / stressed as 
the original construction has been designed for.
I would not risk any important construction depending of such a repaired 
bold or screw, unless it is the only remedy.

Example of such can be taken by bending forth and back of an opened tin can 
lid.
After bending it several times, the lid will crack off.

Again I would say: Safety First before Safety Fast!

Cheers,

Hans
