Engine Bay Nuts, Bolts and Washer Sizes

[Pangsugar]

I am looking to replace the bolts and washers in my engine bay with anodised ones. Does anyone know the exact sizes and amounts per size needed?

I have found a local supplier but am not sure which ones I require.

Thanx

Wow, have fun with that. Why exactly do you want to do this? The vast majority of bolts in any car are automotive grade 8 metric bolts, which have a very high yield strength for safety, and resist corrosion better than lesser grades.

Second, we don't even know what year/model car you drive...

Aluminum bolts are great for show cars, but not for a performance car or even a daily driver. They do not have anywhere near the strength of the OEM bolts, so be preapred for things to fall off/explode.
