Re: Removing concrete anchor bolts
Are the nuts visible ?
Can't you undo them after a good over night soaking in WD 40 ?
I suspect they might turn anyway, along with the part in the ground.
Next.......try whacking them in, and knocking them sideways until they loosen a bit......then a nailbar in the threads might lift it.
There is a retaining wire ring holding the parts that spread the fixing in the ground, once that loosens the bolt will fall out...................give it some welly side to side.
