Polish a Pivot on a Zero Tolerance

[Colorodo]

I have a ZT0452 and I would like to polish the pivot surfaces so there is no black showing. What us the best way to go about doing that? Thank you.

Put the screw in the chock of a drill or drill press, turn it on, and press it against a scotchbrite pad. That's all you need.
