Title says it all. What would you guys do to get this out? Its a number #5 so its quite small. Protip, Ace Hardware sells shitty screws.

Ouch - been there. There was just a thread about this here. There are only a couple of options. Drill it out with a larger bit, but I would recommend a guide block on top.

Stew Mac sells a screw rescue kit. It's way over priced for what it is but you could use it for inspiration. Here is the link and pic - Screw Rescue kit

Here's the video to Dan E. using it. VIDEO I wasn't sure what the drill bit was for but it's for drilling holes the same size as the plug cutter.

Good luck.

Cheers Peter.

Check out some of the screw extractor kits (EZ Out is one brand) to see if they have the proper size and read the reviews about how well they worked or didn't work.

Can you lock a vise grip on it without scratching the wood under?
Maybe put some tape on the top before clamping the screw.

^^What he said. Looks like you should be able to grip it with some pliers.
You could also dremel a slot into it and then turn it with a screwdriver.

I would just drill it to get rid of the screw, then drill a clean larger hole for a piece of dowel. Looks like it will be hidden under the bridge, right?

How could you get a grip on that? Looks like it is 1/16" - 1/8" under the wood. You'd have to take down the wood at least 1/4" to get on it?

Someone should just make a flat drill bit, kinda like a brad point bit without the point and you could use a guide block and drill that out quite easily. That way you wouldn't have to drill too much larger and patch with a larger than needed dowel.

Cheers Peter.

Maybe a small punch to make a dent in the screw top.....get a tiny drill hole and slowly expand the hole with larger drills until you've got to size.

Sorry, on my phone it looked like the screw was protruding a little.

Take a piece of 1/8" brass tubing (hobby shop) about 3" long, and on the end of the tubing, cut half of the end away with a dremel and cutting wheel) so it looks like a "C" on the tip.

Chuck that up in your hand drill. Put it over the screw, and cut a slug out of the body.

Replace with a 1/8" dowel.

I'd first try a reverse drill bit and see if it'll bite the screw and back it out. I've not had great success with that, personally, but it's the least invasive! What'll probably happen, though, is that is just skips/walks across the jagged screw shaft and tries to drill down into the wood beside it.

Failing that, you've got decent options, b/c it'll be hidden by the bridge plate. I think the hollow bits to drill out around the screw are the best bet, either DIY or ready-made kit versions. Get the screw and surrounding wood out and plug it, redrill and never see it once assembled. The funkier method would be to cut off a screw head and stick it with either glue or solder to the bridge plate for appearances and just mount with three screws. Since it's string-through and not relying on the screws to counter the full upward/twisting pull of the strings, I'm sure three (or even two) screws would hold just fine.

Moving forward, if you've got a particularly dense/hard piece of wood, I'd recommend rubbing your screws across a bar of soap before driving them in for the first time, since the screws are cutting their own threads into the wood. Make sure the screw holes aren't clogged with sawdust/drill shavings that could be getting compressed at the bottom and jamming the screws, too! Stick an old guitar string down there and scrape it around a bit, then give it a good puff of air and/or knock against your palm.

Take it to a shop with a cnc machine and ask them to mill the screw out. A carbide mill will cut through that screw without a problem.

I was the OP on a similar thread last week. I basically had to drill out the hole with a bigger bit and plug. Mine was in the butt end and will be covered by a Bigsby.

Yours looks like it could be secured and done more easily on a drill press I'd you have one.

Hollow steel tube slightly larger then the screw. Cut slots on the end. Run it in reverse so it grabs the metal. I extracted a broken trem screw from a Strat this way. I used brake tubing but it was big screw in deep in a hard to access spot.
With this little screw you might have to get creative and look for small diameter tubing someplace. Steel or brass.
A more destructive option is drill small holes beside it and pick it out.

Excuse the necro quote but this was a tip posted many years ago (2009) I have used and never forgotten from an experienced and trusted member, Sgt Pepper.


OK here is the right way to remove a screw with the head broken off on a guitar.
Find a piece of small size brass tube a couple of inches long from a model or hobby shop. The hole in the tube should be a tight fit over the screw. grind or file the outside of the tube to a point. Heat the end of the tube so it won't crack the finish or anything then tap it lightly over the broken screw.
Use a hand drill to slowly turn the tube backwards whilst pushing lightly down and it will grip around the outside of the screw and back it out. Once the screw is removed, a drop of boiling water will swell the wood back and once dry, a drop of superglue will seal it then your ready for the new screw.

Lastly, always remember to use the right size drill for the screw and lubricate screws with dry soap to stop them breaking.

If even a tiny piece is sticking out, these things have worked wonders for me. Better than vise grips so far.


I had just a sliver of a broken truss rod cover screw sticking up and it got it!

Yes, necro post, but thought I would share. These things are great for working on older guitars with super rusted screws.
