i`m in south Florida.
most guys install storm shutters with tapcons.
this person used those lead , hammer-drive anchors.
the client needs these shutters ( accordion-shutters)removed , so the tile guy can install new tile around the pool area.then I have to re-install them.
we`re taking maybe 80 fasteners or more, and some are in recessed niches , where I have maybe 3 inches wide to get my hand and tool 5 or 6 inches in.
can`t use a grinder, no room ,
if I try to slam them out with a chisel ( which is hard as hell), it just really damages the aluminum face . it`ll look like crap

any ideas?

Regular answer: If the nail part is flush maybe you could drill them out like pop rivits. With 80 fasteners that's a lot of drilling, but hopefully it will reduce the amount of force needed to pull them out.

Mad scientist answer: freeze them with liquid nitrogen and shatter the heads with a couple taps. I also understand this can be accomplished with electronics cleaner (canned air).

Probably better than I was going to suggest.....melt them out. :devil2:

really ?
;liquid nitrogen?
is that realistic?
Well yeah, if you are a mad scientist!

Seriously, it might work. Some thieves broke into my buddy's storage trailer doing that. They came out in the middle of the night in a quiet residential neighborhood, froze the big security lock and shattered it with a hammer. Cutting it with grinder would have attracted unwanted attention.

Liquid nitrogen is pretty cheap. The insulated flask you need to hold it is expensive, more than $100. Personally I would try it just for an excuse to buy some liquid nitrogen and freeze stuff.

You might also be able to do it with some canned air. Turn the can upside down and the liquid sprays out and will freeze whatever it sprays on.

here's another thought, why not use an oscillating multi-tool with a metal blade. you'll probably go through a bunch of blades but if you buy them in bulk they are much cheaper

If there isnt room to do this, Id go some good cobalt bits and drill them out.

Pics would help

Zamac pins are freaking awesome, that's why we set door bucks with them they don't come out. I would suggest drilling them out

Liquid nitrogen may end up shattering everything around it as well, like that aluminum you mentioned. Might not be a great idea.

Funny you guy brought that up, when I owned a junkyard we used that to take steering wheel and steering column locks off cars :laughing:
