    Last year i painted my old wheel bolts, and there looking pretty tatty now, i was going to buy some more from MB, but im pretty sure they will just go rusty again.

    Are zinc plated ones any good from the likes of alloywheeldirect etc? i assume proper stainless steel ones arent available?

    The zinc plated ones are OK for about a year, then start to deteriorate.
    Next time I'll try the chrome plated caps that push on as they are pretty cheap

    After going through two sets of original MB wheel bolts (replaced under warranty) on my W203.... I bought a new set of (presumably zinc plated) made by Febi.

    The standard Febi bolts are identical to the original MB bolts, i.e. mat grey/silver, and the Febi locking bolts look much nicer than the bulky MB ones.

    Car now sold.... so can't really say how long the Febi bolts would last.

    But sadly at 4 years old the W204 is now also showing signs of finish deterioration in the (black) wheel bolts... will need to think of something.

    Are there no aftermarket stainless bolts? Hmmm might just paint em again. I find those cap things really tacky looking.

    Never happened on other cars ive had.

    There are many aftermarket options, e.g.:

    Packs of Wheel Nuts and Wheel Bolts from Alloy Wheels Direct

    http://www.alloywheelsdirect.net/option/locking_bolts

    I went for Febi because they looked identical to the original MB bolts (I am starting to think that the original MB bolts are made by Febi perhaps?)

    I bought some rust resistant bolts from Alloy Wheels Direct, and whilst universally well regarded, they started to rust after a few years.

    Unless you can get stainless, any coated bolt will rust especially after being tightened with metal tools. A small chip and the water can start it's oxidation process. Many years ago, I bought some alloy wheels for a previous car and also got hold of some "standard" stainless steel bolts. I managed to buy some sleeves to go over the bolts which made them fit the wheels. For the life of me, I cannot remember where they came from and it was certainly pre internet days.

    Stainless might not be strong enough. They need to be high tensile bolts to a certain spec. Some of the best grades of stainless might just about be good enough but in general stainless bolts are not used in high tensile applications.

    Edit
    I just looked at the link to replacement bolts. They are class 10.9 which I believe rules out stainless completely.

    ^^ This.

    The common/easy to find stainless steels used for bolts (A2-70, A4-70 which are 304 and 316 respectively) don't meet the strength properties of a class 8.8 carbon/alloy high tensile steel fastener...

    I got these in gloss black and they are a very loose fit. So ordered some chrome ones and they are all so loose fitting.
    Got them both to fit 17mm bolts but none fit? Don't bother with them waste of time and money IMO
    Better off painting them, something I'm going to do when I find the time.
    Going do the disc bosses silver hammerite as well while I'm at it.
