New and old bolts

[jim1932]

Is there a trick to "age" bolts and nuts? I am missing a some bolts here and there on my car and hate to see shiny bolts on an old patina car. Not looking to paint them just get that dark grey most of my bolts are. Thinking maybe non-plated bolts and soaking them in something? (yes I know I can put out a wanted for the missing bolts and probably get them, but that is time consuming).

Thanks

Try gun blue/black.

Lay them out in the weather for a couple of years. Oh, that's right, you are in a hurry.

It's more important to get the correct bolts, they will age themselves. The Ford bolts were better steel, no head markings and thicker heads. Try Roy Nausawitz (spelling).

Assuming they're not plated; this is what I did to my spark plugs.

Teflon coated. Satin finish and durable.....

I've filed the markings off new bolts and parkerized them.

Great ideas, how do you parkerize something. I have seen L-100 camshafts that were Parkerized.

You can kill the shine on zinc or cadmium-plated fasteners in a hurry by emersing them briefly in metal prep (weak phosphoric acid).

I always have trouble with spelling his name. Try Roy Nacewicz Parts, (313) 383-3673, fordbolts.com

You live in a populated area. I bet there are plenty of "fastener" stores around. Call then, to see if they have black finished bolts and nuts. I forget the name, but they will probably have what you want.

I took the shine off new bolts by dipping them in diluted muriatic acid (swimming pool acid).......worked well!

I have a friend who's a gunsmith, but I think it involves phosphoric acid???

The result of dipping cad plated bolt (twice ) in gun bluing.

Hey Jim,
I second the 'gun bluing method...also works well on spark plugs. Most gun shops sell gun bluing, but buying/shopping on line give you more choice, IMO

The pool acid (phosphoric) does a quick/easy job..do not put nose/fingers to close to this stuff,eh !

Heat them with a propane torch and drop them in used motor oil. Don't need much heat.

This looks like what I am trying to do.

All my bolts and screws are from Roy, but I am only replacing what I need to. I hate the look of an old car with new bolts.

I remember doing something similar while making M1 Garand sling frogs,
We heated them and then sprayed them with WD40.
Makes them nice and black and lasts.
Just be sure to turn your torch off before you spray!

The proper Ford bolts do look best! However, it's also fun to tinker out in the shop! I love my belt sander... Grinding off marks and rounding bolt heads a bit, then washing with soap and water, then alcohol scrub preps them nicely for a color change. Don't touch, oil from hands will make it spotty. After drying; two dips in the sporting goods store gunbluing for nice blue-grey-black color, torch and different temps and types of oil for purple-brown shades, or order up the nice, machinist "tool blackening" which soaks in deep enough for a little buffy-buff or looks flaaat blaaaack! Then a little oil or WD or wax rubbed in at the end. All these processes are super easy and safe, and fun to watch! Woo-hoo! Science! I've done a lot of acid, whoops, I mean metal patinas with a lot of acid, and chemicals and wax resists and engraving and electricity and paint etc. and I prefer to keep it mellow in the garage at home, chemically speaking. Trying to lay off the "fumes" these days...

The only correct answer here.

Ford boiled fasteners in oil. It makes them less prone to rust and/or seizing.

Drop them in boiling straight weight oil.

It must have worked. I have found that the old original Ford bolts can, almost, always be broken free, while replaced bolts are the ones that break off.
