    Are all screws/nuts stainless steel?

    Hey Guys,

    I bought the stainless steel screws/nuts kit only to get the servo screws for my E-Revo and I found out they are magnetic (check at 0:44)...



    So, I don't think the servo screws and nuts are made of stainless steel, they look like they are chromed steel...

    Basic stainless steel has a 'ferritic' structure and is magnetic.

    Could you specify what you mean by "basic stainless steel"? None of my stainless hardware or sheet metal is magnetic.

    That's because you have austenitic stainless steel, i.e., with nickel added.

    "Basic" stainless steels have a ferritic structure. They're part chromium just like other stainless, only they're still magnetic. When nickel is added (read: more $), stainless ceases to be magnetic.

    The OP probably did get stainless screws...just of the cheaper, nickel-free variety.

    Why worry on those magnetic screw? My spartan is one year old on splashing and water comes in the hull often but those screws doesn't have any rust, so why worry about it??

    Mine is fine. I even use a metal type screw on the servo horn with the Philip head screw type, no rust yet.

    Yes, they're fine. I'm sure they have chromium in there!

    I also have not had any issues with rust on the servo screws and I run my Spartans mostly in salt water. I might add that I use WD-40 on all screws interior as well as exterior after cleaning with fresh water.
