Shes LOOSE!!

Is there any way to grip the nut on the other side with some pliers? Maybe needle nose pliers could get ahold of it.

Other than that, you could buy some 2-part epoxy or another good glue, and dab a bit in between the part that's spinning and the mask (make sure you don't fuse the screw to the nut though ), let it dry so that it can't spin anymore, and then tighten it down.

just get some pliers and hold the other side in place so it doesnt spin.

k thanks

Don't be afraid to Cut or bend the metal to give the Plyers a good flat spot to grip on. Or try a V-force mask

no i like my mask..illl just tighten it with plyers

You should just get a new mask, save you the trouble.

your ignorant...my mask is thermal and its fine its just a little loose...once i get money ill get invision or proteus but getting a new mask just because of the lose mouth cover that IS NOW tightened........ugh w/e
