penned the following well considered thoughts to the readers of

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.


Not recommended.... dissimilar metal corrosion will be very
likely.....

Stainless on Stainless tends to gall so where you need frequent
adjustment, e.g. a backstay with a handwheel, there is often a bronze
nut running on a stainless male thread. It'll be fine with a little
grease on the threads.
