Minimum wall thickness
Minimum wall thickness
(OP)
I have a piece of equipment that has M6 holes drilled into structural steel that I believe are too close to the edge of the steel block. What is the industry standard wall thickness for tapped holes in structural steel? I’ve heard 1 x hole size; 1.5 x hole size. (I’m referring to the edge of the block to the tangent point of the hole)
Thanks for assistance.

I´m not sure I'm sold on the nut comment from a previous reply. A nut has opposing forces so wouldn´t the wall thickness naturally be less than a hole machined into a block of steel?

Check for tearout.
Look at the radial forces in the bolt/stud/etc.
