I might use SS lug nuts on a small boat trailer that dips into the water, but I sure wouldn't be comfortable using them on my vehicle. Stainless steel is weaker than grade 2 nuts.

 

 

John I agree with not using SS for lugnuts, I found a site that I used to replace the ones on my F150. It's www,coyoteaccessories.com I like the ones I used but read carefully some they sell are the same 2 piece design. I bought one piece chrome and the seem substantial but have only had them 7 months so cant speak to longevity.One thing I noticed on these is torqueing them is a little different . You need a little lube on cone mating surfaces which is another can of worms, I have rotated and retorqued them a couple of times with no apparent issues from the lube. Some will say the lube on cone surface is a no-no?
