Ive always been a fan of stainless fasteners but the GS proved the error of that. One of the side case frame mounting blocks has a corroded thread which just sheared off the stainless bolt. The alloy threads had corroded badly and as Aluminium oxide is a larger volume than bar aluminium it just jammed the threads. I managed to drill it out the broken bolt but the threads were clearly chewed away by the corrosion. Its now got a new bolt and good quality antiseize paste but I suspect its unlikely to stop the corrosion.
Rather than replace fasteners with stainless it would be better to invest in a plating tank and zinc plate the bolts. The zinc is sacrificial so will be depleted but can always be re plated. There will also be better plating options.

I also prefer to use carbons steel nuts on stainless bolts because they dont gall or shake loose. But they do need a very good quality plating. Also dont use plated washers unless you really ant to see some rust stains. Zinc plating the stainless threads (if not the visible head) is probably a better option.
