Is there a proper name for the sort of bolts used for brake calipers and to bolt hubs to discs? I've been using a 1/2" double hex socket so far and it has worked but too much use of a normal socket with a windygun has killed it and I figure if there's a "proper" tool for the job it's probably time to get one as my impact sockets are all single hex and so don't fit.
