restoring nuts and bolts

**Canuck** · #1 02-23-2008, 03:14 AM

I have a few hundred correct style Nuts and bolts that i am wanting to restore to freshen up my cars. The Nuts and washers will get a silver cad or Zinc finish. I need advice about the bolts. I have heard the terms phosphate and black Oxide finishes for bolts used on rad supports and attaching some of the sheet metal. Which is correct? A fe local shops can do the black oxide but they stated it has an Oily finish.
Advice?

Black phosphate kits can be purchased from Year one and you can do your own nuts and bolts

I just got the Manganese phosphate system from Vern Owens in south carolina, haven't used it yet, supposed to be the way to go for bolts...it leaves them the color of pencil lead. I'll post when I do my first batch. Black oxide has an oily finish to protect it, as alone it has very little rust resistance. The phosphate Vern sells stands up to a Military spec salt water test...

Try this guy Sparkys Carburetor Service www.sparkyscarbs.com. He has done all of my plating for me. His webpage has a section for this. The parkerized parts will be oily when you get them back. But you can just clean it off before installing them.
