How do you remove a bolt from the aluminum of a cold air return?

Question

My associate is trying to remove a safe from a home. They got all the bolts out besides one which appears to be bolted into the aluminum in the cold air return. They need it out asap and don't have time to hire someone to come out here and do it. Any recommendations on how to safetly remove it without harming the aluminum?

A thin, non-ferrous, metal cutting saw blade. You want this to prevent heat build up. You might be able to get one of these blades for a reciprocating saw if that saw will fit in there. Or the blade on a hacksaw.

Hi Kristi, if it is just seized you could try spraying some WD-40 or a silicon based lubricant to loosen it.

Hello,

You could try WD-40 - leave it for a while and then try to loosen it. or you could try to warm up the fixing and then try to loosen it. Good luck!

WD40 Or PB Blaster should loosen the corrosion. Heat the bolt with a propane torch. Use vise grips and tighten the bolt just slightly. Should break the corrosion. Then just unscrew it.

You could get a hack saw under the head and saw it off

Dee · Answer

I would do one of two things. I would either spray with silicone or WD40 and see if you can loosen the bolt. If not, take a hack saw and cut the bolt out leaving the body in the aluminum.
