Also, have you considered power-coating? I've used powered paints on

Hi Mike,

I'm thinking ahead, and If I get to the point where I make alot, I
don't want to have to paint the screws. I think i'm just going to go
with a black oxide finished sheet metal screw.

Thanks
John

I really like the "High performance serrated thread" screws from
Mcmaster carr, but they only come in a silver zinc finish.
