Much better c10 for longevity going for the flanged race hex over the domed , when choosing aluminum . The domed , even when careful , tend to scar up quickly in the tool slot in my experience in black aluminum .
I went domed black titanium in those bolts , all the bodywork including front guard actually , at the expense of some extra weight , the gloss black ti dome bolt is a beautiful fastener .
Pro bolt do a nice rotor bolt in ti if you are interested Willie , sets available for front and rear wheels and colors too .
Also , pro bolt do an aluminum threaded sleeve , in all sort of short lengths in M5 , M6 and M8 . They used to supply them with bodywork fastener kits when that business first got started , then they swapped them for cheap plastic , which don't last well if you are ham fisted .
I use them with my ti bodywork fasteners for a long term lightweight fastener setup .
