I have noticed bolts and nuts are most likely to seize if they are of the same material, if corrosion is absent. Hence brass nuts on steel exhaust studs won't seize.
Stainless on stainless seems to be the worst in my world, the two parts commonly gall during assembly and seize upon a removal attempt. When I come across seized steel screws in my work they won't release until heated to glowing red. At this point they are damaged and need replacement but at least they are extracted. If it is in wood that cannot be damaged by heat, I believe you'll have to destroy the bolt without heat. Same if it is in heat treated steel or aluminum since you can't reheat that heat sensitive substrate. I suppose, really you just can't use heat if it will change the substrate in some important way. jg On Thu, Jul 1, 2021, 17:11 Mark Jones <flyk...@gmail.com> wrote: > Thanks all. > > Mark Jones > Oldsmar, Fl > > N771MJ “WunderBird” > www.flykr2s.com > flyk...@gmail.com > > > > > On Jul 1, 2021, at 7:24 PM, Jeff Scott <jscott.pla...@gmx.com> wrote: > > > > Heat.
