Is there any reason NOT to replace standard steel screws, nuts, etc. with stainless versions? I hate seeing rust anywhere so I am thinking as it shows up on fasteners, I will just replace them with stainless ones. Now I know that stainless is "softer" than, for instance, high speed tool steel. However, fasteners are not made of HSS, and many are stainless now anyway. Even though some of the screws may look highly specialized, almost all seem to be standard metric sizes available at a good industrial fastener supplier, though not a regular home center or hardware stores. You can get most of them in regular steel there, but for stainless you have to go to the specialists or online. I know they cost a little more, but not enough to even think about because there are not that many.
Any comments from the pro mechanics and engineers?
