Pretty rare to come across a left handed thread , you have to admit , percentage of all fastners as a whole , maybe 95% to %5 , so let me take a shot at a new saying :
" Lefty loosey , righty tighty , and if that don't work then try it visey-versay "
Old Mopars and old school heavy duty trucks with Budd rims are two lug nuts I can think of that are left handed on one side the vehicle and right handed on the other
I am saying it is rare and when I think about it , I came across one yesterday , on a swivel for air
