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 concrete. How do I remove whats left of the bolts? I attempted to drill 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.
