Title: stainless fasteners
Post by: billywingnut on April 06, 2020, 05:49:48 PM: Having got my bike out for service in the hope that I can ride it again soon, I notice that the fasteners holding the cam cover are starting to rust. I have not had these zinc coated when I restored it. I 'm thinking of replacing these bolts with stainless (with copper grease).
What are your feelings on the use of stainless

https://www.titane-services.eu/Titanium-screw-Hexalobular-socket-raised-countersunk-head-ISO14584-Grade-5-Diameter-M5 something like this for points cover.

He has shouldered set screws if you want them.

Other sellers are available. ☺
