I built a picnic table several years ago. It took a hit from the snow

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?

I take that to mean the bolt is counter-sunk? If so, how did that
happen? I mean whatever you used to counter-sink the bolt should be
the same device used to remove it.

If it's a carriage bolt, it has a nut somewhere. Can you attack it
from that direction?




I believe that Liz is saying that when she turns the nut, the bolt
turnes with it and the square under the bolt head reamed out the wood,
possibly because the nuts are a bit corroded onto the bolts.

If the nuts are accessable, she could buy a nut cracker and split them
so they'll slide off the threaded part of the bolts, then drive the
bolts out enough to grab the head and pull. Then buy some new nuts to
suit.

Sears sells nutcrackers, and so do most auto parts stores:

Good Luck,

I think they are called nut splitters.
