The "Holy Grail" ?
Discussion
Eternal life? Yes, but for your bolts. High Tensile stainless steel bolts .
Perhaps I have a little OCD but the rusty caliper mounting bolts have always bugged me so after a bit of searching I found a company that can supply stainless at the equivalent of 10.9 tensile strength. That's the good bit.
Ironically my search took me all around the World only to end up at a supplier here in Redditch where I live. Another good bit.
Now the not so good bit, only sell in box's of 50
So even doing front and rear calipers that'll leave me 42 spares ( I'm talking M10 x 30mm for the 240 or 260mm brakes, no good for big 888/887 calipers which are M12).
With VAT, postage etc. I think they'd be about £8 per set of four.
Please form an orderly queue........

Dear Concerned of Norfolk,
from my discussion with the supplier and what I've read in articles like this, combined with my experience of using stainless (mainly A2 70) bolts on my car and having seen stainless fixings used on air conditioning plant that stands outdoors in all weathers I don't think there is an issue.
But, of course, everyone must make their own decision.

When in training they show us what can happen. To do that they put a small bore pipe in a beaker of salt water and put a Bunsen burner under it. Before the water even gets to boiling the pipe shatters where it is in the water and comes out looking like a flower. For the brakes or suspension, the stress comes from the torque, the salt from road dirt and water and the heat is all that is needed, for brakes where that comes from is obvious.
Mark, brakes are obviously a serious matter and I don't mean to make light of your concerns or knowledge, but I'm really not getting the pipe in boiling water thing?So, cooking my peas for dinner last night I had boiling salted water in a stainless saucepan and dropped in a short length of 1/2" stainless tube. stirred it with a stainless slotted spoon and fished it out with stainless tongs.
Apart from my peas tasting "funny", perhaps piece of pipe wasn't as clean as I thought, nothing happened.
Stainless exhaust systems get hot and cold, get sprayed with water, possibly salty in winter, but don't self destruct?
Stainless is often the material of choice for replacement caliper pistons, bleed nipples and braided brake pipe end fittings.
Swirl pots, header tanks, cooling system pipework, the list goes on....
Da Dah, we have bolts (and washers) 
Fitted mine today, couple of little points...
1. Heads are, unusually, 16mm not 17 as you'd expect on a 10mm bolt. 16 is a bit of an odd size, if you're struggling a 5/8" AF is a perfectly good fit
2. Most of you will be fitting these on the front brakes (apart from those with rear discs), they end up very close to the disc, 28mm long would have been ideal but that wasn't an option. If you're using spring washers as well as the flats they'll be fine otherwise you may want to cut a "smidge" off each one or use double flat washers.
Whichever option you choose you must, of course, also use a reputable "threadlock" compound.
3. Tightening torque, manufacturer says these are good for 66Nm, the figure I have from TVR (Chimaera but same set up)is 58-60Nm. Thats 44ft lbs to any old school guys out there
If you're still interest it's £8 for 4 or £15 for 8 inc. postage please pm me your address.
Should I actually sell every last bolt I will end up a pound or two in profit, that will go to Longers next charity bike ride.
