Removing an strap button and I have sheared off the screw right where it meets the body so the broken off part is flush with the body and no where to grip to back it out.
Any suggestions ?
Thanks folks !

Drill a new hole as close as possible to where the old screw was. Install the strap button with a new screw, and use a felt washer. The felt washer and strap button should cover up the old screw.

What kind of guitar? What kind of wood? Was the screw really tight, or was it a fluke?

These are difficult to remove without special tools. The generally-accepted method it a tube drill. You can make your own from a piece of steel automotive brake line. Cut a piece about 2" long. On one end, use a knife file or a Dremel with a diamond wheel to cut a series of small teeth around the circumference. Don't overheat the metal. If it turns dark in color, you've cooked the steel and it's too soft. Dip it in water as you work to keep the metal cool.
Next, measure the diameter of the tube and drill an identical-size hole in a small piece of wood at least 1/8" thick. This serves as a guide for the drill as you start the cutter into the wood around the broken screw. Once the cutter is in the wood about 1/4" you can remove the guide and continue. Drill down at least 1". As you drill, you have to frequently remove the cutter to clear the chips out because the wood you're removing has nowhere to go. A little wire brush helps here to pop the chips off the cutting edge of the cutter.
The cutter slices the wood surrounding the screw. You can use a small punch or nail set to knock sideways the plug of wood with the broken screw in it. Gently push it around and the plug will break off and you can remove it from the hole. Fill the hole by gluing in a dowel flush with the surface.
Drill for a new screw and replace the button.
If you don't want to try this, Wish's advice above it the 'field expedient' method used most often.

Peegoo and Wish have it right. Personally, I leave it in. Leave it in, drill a new pilot hole as close as you can, install new screw and button.

Peegoo took the words out of my mouth. I made my own tube drill from a socket set male to female hex extension. I used a 5mm drill bit to thin and smooth the female end and my dremel to cut out 4-5 angled teeth, the other end just goes into your drill then just follow the instructions above.
