I've been using them for years and will continue to do so.
as olChris says - lubrication on assembly is essential, as the threads can gall and make a real mess of themselves.
Polished or sandblasted to look original, they just stay that way. Marvellous :wink:

Using low grade stainless, like what is often used for general hardware but also by some suppliers making kits and hardware for Commandos, can definitely create issues, especially in critical applications
High strength and quality stainless can be used anywhere with great results
Proper lubrication is important as mentioned above
Be sure to check with your supplier what grades of stainless was used for specific kits and if they cant/wont answer that question, then its likely that its a lower grade stainless that was used. Proceed with caution unless its a general application like mounting body panels on your bike
Unfortunately some of the lower, most commonly used grades like 303 and 304 also are the ones less likely to corrode and favored by many because of this
Some of the harder, higher tensile strength, types like 17-4 are not as corrosion resistant
So just be sure you know what you are getting and shop smart. Then stainless will work great for you

Yes, some stainless fasteners can be quite stretchy (elastico) and have different torqueing characteristics. Another way to say it would be, standard torque specification can be very different if the material of the fastener is very different.
Go ahead and bling things up but use caution on critical torque sensitive items like heads.

I just had about 20 lbs of parts Cadmium plated. I had axles, bolts and nuts, exhuast nuts, intake manifolds(Triumph) Sprockets. springs etc from about three motorcycles. I took the Nortons head off and did all the nuts and bolts. The total cost was only $140.00. I think it is a lot more economical than changing everything to stainless. It is worth thinking of as an alternative. It is pretty durable. I have a bike that I had re done in 1992 and the head bolts still look nice. You can also get electroless nickel plating for about the same price if you prefer that. The only problem I had is that I forgot to get half the magneto strap done for my BSA so now I might have to put in another small batch so that I can get that bit done. The ideal time to get this plating done would be during a total restoration when you could just get it all done at once.
