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.
Do you need to remove them for some purpose, or are you just concerned
with the busted stubs sticking up? If the latter, just grind them down
flush with a 4" angle grinder and let it go. Patch and paint as necessary.
replace "roosters" with "cox" to reply.
Depends on how well they are in there. You can use an "easy out". available
at any decent hardwqare store. You drill a pilot hole, insert the easy out
and with a wrench try to turn the lag out. Once started it can come easy,
but if well stuck in the concrete it may be impossible.
I would try drilling with a good high speed drill bit. It may be
sacrificial, but use one at least the same dimension as the bolts or maybe
start with something bigger then go smaller. Use a hammer and a pin punch
to get a flat surface for the drill bit to sit on.
Yes was going to say; grind the old ones flat, mark a significant
punch hole to get drill started. Use good drill bits same size as
bolts and drill carfully, you may break off the drill bit which could
give you another problem!
OR: Grind flat, move new railing half to one inch over and drill new
holes in concrete?
Do the new railings have to have identical mounting points as the old?
