    Be careful where you use them as they are not high tensile and as such not suitable for all applications.

    agreed! 316 and 304 stainless are only approximately the equivalent of grade 4.6 in "normal" steel.
    common grades in "normal" steel are 4.6, 8.8 and 12.9 the higher the number the greater tensile strength...this is normally written on the head of the bolt, if there is no marking assume it to be 4.6

    dont use stainless for any high tensile applications.

    I have replaced all screws on my bikes as they come off with stainless steel cap heads (allen key) but only fairings and ancills and always with grease

    If you read the spec sheets for stainless steel, 316 (A4) is very close to the same strength for 'normal' steel, certainly strong enough for applications on road bike high -stress areas like disk bolts and caliper mounting. I wouldn't use 304 (A2) in these places though.
