Cannot find metric bronze screws for my diesel water pump, so replaced
em with SS ones. Yanmar uses these awful Phillips screws on the water
pump covers that get messed up quickly and really dont hold tight
either. I have used SS allen ones.

I suppose it all depends on the alloy of the stainless and the alloy
of the bronze but they use stainless scleras on bronze direct burial
ground clamps.

I looked on the Galvanic series and most SS is close to bronze.
However, Yanmar used what look like bronze screws instead of SS
although SS is prob cheaper. Weirdly, the face of the pump that gets
removed when changing the impeller is SS held by the bronze screws.
