Broken off bridge mount screw...

Would appreciate advice/suggestions as to what to do with a broken off bridge mounting screw. Other four screws are fine and bridge seems solidly mounted. Doesn't seem to affect sound or ground. Leave as is, try to drill out.....any opinions would be greatly appreciated.

You could try drilling it out with with a screw remover. It is like a drill bit but the tread is reversed and you have to operate the drill in reverse

If its causing no issues, let it be. It's only going to be a problem if it comes to mounting a new bridge.

Otherwise, yeah: screw removers or I've had to drill out around the shank of the screw to get a decent grip on it to get it out and then fill the resulting hole with polyester padding, or a piece of dowel - the method of filling will depend on the guitars finish! - but it's easy enough to do; normal rules apply....

Think it through and take it easy!

If there is enough of the screw showing, you could dremel cut a slot for a flathead screwdriver.......it works if the slot is thin enough.

Leave as is and superglue the head to the bridge.
Isn't going to make much or any difference as you say.
Which guitar is it anyway?

Thanks for the advice/opinions fellas...I purchased the guitar off eBay, and unfortunately it came to me with the screw head busted off. It's a Ray bridge from the APII Thor Sound 400 I recently purchased. It doesn't seem to be a problem so I think I will leave it be. It's under one of the saddles and I didn't even notice it myself till I changed the strings. Thanks again!
