The 1/4" lag bolts for the railing supports in the front concrete porch
steps have rusted away leaving headless 1/4" lag bolts imbedded in the

them out using an 1/8" drill bit but it could get started.

How can i remove the bolts? Some of the bolts are not broken off even
with the concrete some of them are headless and bent slightly to one side.

cut a slot in them with a dremel and use a screwdriver?

using a left handed drill bit could back them out enough to get a pair of
vice grips on them


I once had to remove anchors (nails driven in with an explosive charge)
from concrete and simply used a circular saw (w/ eye protection).
