Surface Finish No. 5
Surface Finish No. 5
(OP)
Hi Guys,
I am looking for the definition of "Sutface Finish No. 5".
What standard is it based on?
and
How can I measure or verify it on a piece?
Thanks in advance,
:)

Is it stainless steel?

5 is not a preferred number in either system. Micro-inch callouts would be numbers like
4, 8, 16, 32, 63, 125, 250, etc.
and the preferred metric ones would be
0.10, 0.20, 0.40, 0.80, 1.60, 3.2, 6.3, etc.
A finish of 5 microns would be pretty coarse, on the order of 200 u-in and equivalent to a sawn or drilled finish.

#5 would not be common, but for some reason a certain shop in NC (old customer) preferred to use odd numbers, specifically 1, 3, & 5.
