Can anyone shed some knowledge based on experience on whether it's safe to use tapped holes instead of locknuts?
Lets say you wanted to attach some square tubing to the side of another piece of tubing like this:
Is it safe to just tap and screw a bolt into the block that I have between the two tubes, or would it be better to just run a bolt through the whole thing and use a lock nut on the end of the bolt? The block is ~.5 inches thick in the middle.
If I'm not being clear enough please tell me.
