Surface texture designation

[chedderhead]

What does the designation of F.A.O. under the surface texture symbol in a mechanical design drawing mean?

Thanks in advance for any help you can give.

"finish all over?"

I believe arto is correct.

From my experience, FAO = "finish all over" which is an older practice and is not defined in the current version of ASME Y14.36.
