All the nuts are already rusting. They were on the truck for almost 6 months. Needless to say I am very disappointed. The seller refused to replace the rusty nuts but offered new ones at a discount. No thank you. I don't need 24 rusty nuts anymore. I really want the seller to do the right thing and replace the nuts with stainless ones. The problem, of course, is that if you live where it rains and snows, all the nuts they sell will rust in a few months. God bless you.
