If this is the style with the 'sheet metal overlay', your best bet is to just get solidly made ones.
The sheet metal cap always turns into deformed garbage, no?
Seriously, all the ones I've ever seen perish.
Also, as a point of humor, there's a battle cry about McGard locking lug hardware on the Volvo fora....and that is to remove the McGards while you still can. Either they rust up or the key contours crumble away.
Again, these are bolts. McGard's lug nuts might be good in that REGARD <<get it, get it?
