Benn:
You must break the bolt or cut it.
I belive Unirac has a white paper on galling.
We use anti-seize on any bolt we can not slide out sideways easily. This
includes any battery bolt and any non-toggle racking bolt other than end bolts.

So this was a first for me today...
I've had racking bolts gall before, but today while bolting a battery
interconnect cable on a battery post, the nut galled about 3/4 of the way
down the post. (Threaded 'bolt' posts, not single or double hole flag posts)
I've gotten pretty good about using anti-seize on all stainless racking
bolts but never considered using it on battery post bolts before.
I spun the nut on about half way by hand then got a couple cranks with the
wrench when the nut suddenly tightened up. Thinking that the thread might
have been damaged, i instinctively began to back it off but got less than
an eighth of a turn out of it and it was completely seized!
Two things...
1) while i go re-read all my info on galling, is it common practice
amongst you battery savvy wrenches to always use anti-seize on battery
posts? I'm thinking that it is for me, now! (only on the threads, not
between the lug and the post)
2) now that i have a nut seized 3/4 of the way down the post, and the lug
is still quite loose, what would be the best course of action?
I did email the mfgr and am waiting for their reply, but in the meantime,
solutions i'm considering... using a hacksaw to cut the nut off and
hopefully be able to re-cut the threads, weld the lug onto the post (Bob
E., i believe you mentioned welding 'interconnects', would this be a
solution here?)... thats all i've got.
hmmmmmm...
