minimum plate thickness for tapped hole 1

[RacingAZ]

I think I read this here before but I can't find it anymore.

What is the absolute minimum steel plate thickness I can use for a tapped hole to put a 1/2" dia. A307 bolt? I mean minimum from a fabrication stand point only.

I'm not looking to develop the bolt capacity. Very lightly loaded, if there is a load at all (100-200 lbs. tension).

oops ... to me "thin" plate is < 0.1" ... if you're 3/16" thk, self tapping screws should be enough (so long as you dont' over-torque them) ...

rb- I'm actually looking to use a bolt, not a self tapping screw.

Ron - Great point. Thanks!
