I attempted to use my $24.00 air rattle gun on a Victa crank nut on a mower that had sat in a partially exposed rusty chook shed for many years and for the first time, this cheap and cheerful tool couldn't budge one. I fetched my 12 volt car lug nut remover kit I keep in the boot which works with a slow series of heavier hammer blows, once per second, and it started to move it after about ten hits.
It has a claimed rating of 500nm from memory.
Whenever I have loosened lug nuts for people at the side of the road, they are always impressed
. It plugs into a 12v power socket or direct to the battery via alligator clips. Not bad for $50.00.
