William,Luckily, the battery was new and under warranty and the mfgr, Surrette, was very helpful and immediately offered a replacement.Had this been out-of-warranty, then yeah, cutting the bolt/lug off would've been my best (only?) option. Still wondering about welding it in place? A battery shop i deal with in town suggested that they could cut the damaged post off then tap a new hole beside it and insert a new (headless) bolt/post. Lesson learned.... (as you said) use anti-seize on every bolt that cannot be slid out or otherwise easily removed! It's just like insurance, sometimes seems unnecessary and rarely useful, but when sh*t happens, you'll be glad you used it! benn

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.

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... benn DayStar Renewable Energy Inc. b...@daystarsolar.ca 780-906-7807 HAVE A SUNNY DAY _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org No virus found in this message.
