Hi,

I am looking into a list of componants for assembly of silencer and exhaust piping of a bus, and I am stuck with the terms "FP" and "CP" in the following list:

- SCREW M10 X 25 X 1 FP PLATED
- SCREW M10 X 35 X 1.5 CP PLATED

What do they stand for?
I have been looking on the Internet but cannot find anything.

Thanks for your help!

I imagine it is about the ability to withstand the heat and there ability to last in the environment.

There is a company called Fastenall. They specialize in all kinds of nuts and bolts. Look them up and see if you can call them and they may be able to help you out.

FP seems to be zinc plated and CP is likely chrome plated but in some situations means copper plated.
