Rallye wheel center cap screw mount holes

Never had a problem with stainless and aluminum. Stainless and stainless now that is a problem. I work on underwater stuff, so anti-seize goes on everything and blue grease coats all non threaded part interfaces.
Buddy was putting a lwer unit on an outboard motor,refused to follow instructions to anti-sieze or threadlock the studs. One didnt thread in all the way before it locked up. Anti-siezed the rest and they went in fine.
