Removing carriage bolts from wood
I built a picnic table several years ago. It took a hit from the snow
plow this winter. It's worth repairing, but I can't undo the carriage
bolts. The square part of the bolt head strips the wood when I put a
socket on the nut. Next weekend I'll try pounding a screwdriver under
the head parallel to the surface of the wood to engage a flat side of
the square. What do you experts do?
