How to treat hardware, nuts and bolts?
I am of the opinion that today's modern hardware is no way near the quality of the OEM stuff, (I think there's less "metal" and more "filler" but a metallurgist I am not, metal head yes!)hence I try to preserve the original nuts and bolts when ever I can, plus sometimes you gotta reuse something that is no longer available in the aftermarket world
recently I finally got into media blasting, and oh my goodness what a game changer (yes it took me about a month to dial it all in, little things, like oh being able to see inside my media blasting cabinet, lol) anyway so now I have thse "naked" bolts, now I also do my own powder coating, but that is very time consuming for nuts and bolts, and even if I was going to powder coat them I don't powder coat the threads I also tried Eastwood cold plating kit, I don't recall if it was zinc plating and bluing but that sucked either way I also tried the heat them up with a torch and dip them in old used engine oil, but I hear that changes their strength properties so I only do that for ornamental hardware (like the grille, etc) and not structural (actually works great and the nuts and bolts stay black and don't rust) so I am open to suggestions |

Re: How to treat hardware, nuts and bolts?
This is something I want to try
There are lots of video's out there to do (Electro-plating) home plating. This is the simplest one I found. Beside his annoying (Second person) voice

Re: How to treat hardware, nuts and bolts?
thank you all for your feedback, here is an excellent video on using motor oil to blue them bolts, he does a really good job of explaining the color changes as you heat up the metal

Re: How to treat hardware, nuts and bolts?
Nice video.... I'm somewhat suprised, knowing how scientific you are, that you wernt using a temperature gun on the bolts when you heat them... I know it dont take much to do it..weve treated alot of metal in oil at the farm over the yrs..

Re: How to treat hardware, nuts and bolts?
I have used the Caswell plating black oxide solution with good results (link below). To keep them looking good you must use a sealer on them after the black oxide treatment. I am going to watch the video and see the results for comparison.

Re: How to treat hardware, nuts and bolts?
What I do with all my bolts, is soak them in EvapRust. Rinse and drop them in oil. Good to go.
The brackets were sandblasted & repainted.m

Re: How to treat hardware, nuts and bolts?
I’ve got a glass bead blaster, but what I do with my small bolts etc, is put them in an old vibratory tumbler that is left over from where I upgraded my reloading tumbler. My arthritis sometimes makes it difficult to hold small stuff to blast. Put it in the tumbler, turn it on, and walk away.
I do have a variety of tumbling media, so may change sometimes to something more “aggressive” (ranges from corn cobb media to stainless steel pins) |

Re: How to treat hardware, nuts and bolts?
No heat. Most of the time it’s overnight. The ones that are really bad, I take them to the sink and use a small wire brush on them, and then drop them back in for a few days. They can stay in for days on end.
I do all my seat tracks also in EvapoRust also. I have a plastic rectangle planter that I filled with EvapoRust. Then I submerse the entire set of tracks down in the fluid. The next day I take them out and rinse, and immediately blow them dry with the air compressor nozzle. When they are good and dry, I repaint them. And then lube the bearings & rollers.

Re: How to treat hardware, nuts and bolts?
Greg,
You might try the local home store for concrete etching solution. I think the name around here is Etch-n-Prep or Etch and Prep or something in the paint or concrete toys sections. I wouldn't leave parts in it longer than necessary depending on how diluted it is. It's phosphoric acid and I suspect it's the base for numerous rust removal stuff like Evaporust. Note that you need to dilute it and don't get it on concrete--it dissolves it. It also removes galvanized plating in case anyone cares. |

as far as diluting it, well maybe 10 years ago yes, but I know for a fact they have changed their formula since then here in California, you can almost drink this stuff these days it's that weak |
