How to remove stand off's from case?

[bmb2296]

This may seem like a really stupid question but im a noob and this is my first build. I have installed everything on my MOBO cpu,ram etc.. now im just getting ready to mount the mobo in my Rosewill patriot ATX mid tower and this mobo (ASrock 990FX extreme 3) has 7 stand off's for to screw in but the case came with 9 and I need to move one of them to make it fit properly what tool would work?

thanks 😀

pliers.

Those stand-offs should not be screwed down very hard. Counter-clockwise to loosen.
