Thanks to all who responded to my previous posting ( http://tinyurl.com/69sld ) regarding replacing rusting fasteners on my bike with stainless steel equivalents.
A friendly engineer at work got me the bolts f.o.c from our suppliers. Apparently they view any quantity less then 000's as "samples"!
Hopefully, they'll be up to the job. The engineer says that QA usually performs hardness and strength tests on a sample of each batch used in actual production, and the supplier hasn't let us down yet.
I started installing the bolts yesterday. Cutting stainless steel bolts to length with a dremel is not much fun, btw.
