How long are trem claw screws on a fender (I think it's a fender vintage 70's). I was wondering if you can unscrew them too far and they'd fall out. If so waould this damage the holes thread when you screwed them back in and would you be able to screw them back in?

Tremolo claw screws are #8 - 1 3/4".

If you screw it all the way out, it will screw back in. Don't worry about it.

No it won't damage the holes to screw it out too far. Don't worry about it.

If it does wallow out the hole, dip a toothpick in some wood glue, put it in the hole, break it off flush, put the screw back in. Fixed.
Hmmm...I wonder what this button does...
