Is it bad to tighten a screw too tight?

[Chapel]

I mounted my motherboard but I think I tightened one of the screws a little more than necessary. I wasn't using an electrical screwdriver. Just by hand. I was going to untighten it but I have to push down pretty hard to get a grip in the screw and thus the motherboard slightly bends. I don't want to bend my motherboard T_T; I don't know how far is too far with mobo's so please enlighten me. Thank you for your time.

Just realized that this is in the oc section. Sorry, requesting a move.

This guy acts like your the only person to ever ever ask inthe wrong section..sheez. Anyways, YES it is always bad to overtighten a screw. By definition. But if it is tight, and you dont need to remove the board, then no harm no foul. As long as you didnt crush the board your OK.

I slight bend of the motherboard wont kill it. Im curious as to why your mount point is bending though? Do you not have a standoff under the board to the tray?
