i want to replace the bolts that hold the rotors and calipers on my scg with stainless ones,do these bolts have to be high tensile? and if so where can i purchase them?

Call me old fashioned, but when your life depends on something, you really should be fitting the best kit...

I am sure stainless fasteners will be just fine, but I would be fitting plated Grade 8 / 12.9 screws and bolts...

Best place for plated Grade 8 fittings is your local HD dealer...

.....form over function re. safety related fasteners = Darwin wanker types

Apart from that, if you really want to risk your life for the sake of shiney fasteners, I'd be amazed if you could find anyone supplying stainless bolts for the rotor......they're stepped/shouldered.......and the Palmer items are nothing like good enough IMO......I hope he has really, really solid insurance selling shite like that

Shouldn't use plated anyway. Hydrogen embrittlement.
the hydrogen can be released by baking after plating, but I wouldn't risk it with brake parts.

You can use NAS bolts, aircraft Quality in imperial sizes.

Oil black then Mickrick?

The ones I used on my car discs are black socket head jobbies yes, but they're metric 10.9.
The NAS bolts are plated though, but obviously the QC is top notch, and I think they only come with hex head. Some are pre-drilled for wiring too.

Indeed some NAS (and AS) bolts are plated.

Oil black is probably fine for a car that never sees rain like yours

Ti. Awfull galling stuff!

But isnt this the same problem with stainless in alloy and can't it be solved in the same manner?

How do they solve the galling problem in the aircraft industry?

Personally I have never had problems with stainless fastners on any of my bikes but they have always been coppaslipped. When I got my S1 it had most of the fastners replaced with Titanium and I have not had a problem removing any of them and they were not coated in anything that I could see. I admit that my S1 has never seen serious winter riding in its life but does galling require external corrosion factors as well?

I am looking for enlightenment here (pardon the pun) as motorsport and the aircraft industry seem to be the go to guys for the latest strong and light materials but I would love to know the pitfalls when used day to day on our roads.

NAS bolts are surplus aircraft military stock. Very good quality.
Ti isn't stronger than steel size for size. But it's lighter.
I looked at Ti for some driveshafts, and they use a steel called 300N I think it was. They still use it in F1.
A bit of Teffgell will stop SS from siezing/corroding in Alluminium.
