Fork N Torque will use about 200 to mount armour

You could tap in a thick walled box section. A guideline for treads depths.
In steel and Titanium bolt size. M4 is perfectly possible in a 4mm thick plate (or box section wall).

In ali and other soft alloys,boltsize *2. An M4 needs 8mm of flesh.

Bronze and simular boltsize *1.5

hi alex

All ya gotta do is drill a 10mm hole in one side (outside) of box section...insert rivnut then if ya have the special tool just close the jaws...if ya dont have tool follow instructions on addy given.....i also give each one a couple of tack welds to really make sure it dont come loose !!
