DIY at home original Black Oxide Phosphate OEM Restoration of nuts & bolts

[@samnguyen8426]

That is the most organised workshop ive seen

[@bertkutoob]

I wonder what his wife thinks about his expropriating her kitchen. Granite tops and oak cupboards in a workshop? I call fake! 🤣

[@sabinabrozynski9215]

I have done this process a number of times and I have found that coating the item with wax works well. I melt some wax in an old pot and soak the item for a few minutes in it and then take it out and place it on a wire rack. I then hit the item with a heat gun to melt off any excess wax.

[@carcraftgarage5430]

Just a quick tip for anyone without as much time or money.. buy high temp iron furnace or grille paint, spray it on the cure it immediately with a heat gun. Makes it chip resistant when assembling and looks just like stock black oxide

[@jimnuna2022]

Thank you live in CA and no one does this stuff anymore. Great help to do myself

[@johnnyjohn8073]

Yesterday I went to my garage to pull out all the nuts, bolts, screws, washers, hinges, etc. from my 79 Caballero (El Camino) in order to put it back together, only to realize that they are all rusted after last year I worked so hard to remove paint & rust off them. Sure, I also etched them with metal & concrete etcher from Home Depot ( I guess same as Muriatic Acid), then I primered them with an etch primer, then epoxy spray painted them...to no avail. So I've been researching today into zinc or nickel plating them but I would actually have to wrap each item with copper wire. I won't get into what else is required...but just having to wire each item is just a daunting task. So I'm glad I stumbled on to your video on how to black oxide the parts. Long process as well but at least I won't have to tie each part with wire then attach DC voltage to 2 separate metal piece dipped in the cup with, attaching a negative & positive leads. Needles to say, black oxide nuts & bolts is more original to these classic G-body classics so I'd rather follow your example. The black oxide concentrate by Caswell on Amazon is $31. I'm sure I'll be happy with these results & following your instructions. Thank you.

[@Good-Enuff-Garage]

excellent demo, question is how well do they hold up, it's almost 4 years later now, so I would love to see how rusty they are now? not trying to be rude, I just played this game before and the cleaning is the easy part, keeping them rust free is the hard part

[@glunaphotography]

Wonder how they look now

[@bootygoblin784]

My god man. I have just finished painting my harley all black and was breaking my head open trying to figure out how to buy black bolts cause my old ones keep rusting on me. You are a godsend!!! Thank you very much.

[@tarstarkusz]

You can turn them black by just electrolysis rust removal. That is a side effect of using electrolysis to remove rust.

[@alfadoctor1]

This just resolved my problem on the restoration of my LOBO bolts that are factory black. Thank you!

[@oldmanpottering]

Hey mate, thanks for the video, loved the no BS style, straight to the point and informative ........also loved the bloopers

[@davidbrogan606]

Good job. Ya know, when measuring, it is good procedure to measure the small amount in a more accurate narrower beaker. The reason is that with the larger beaker it is so easy to get the water a bit off and that throws off the amount of oxide resulting in an improper ratio. Example: If you mistakenly had placed 9 1/4 oz water, then you'd only have 3/4 oz oxide and a 12:1 ratio. I spray trees for a living, so this is something I do all the time. I mean, you can do it the way you showed, but you should bring the beaker to eye level and do it carefully, reading it at the meniscus, like we were taught in chemistry class.

[@kenhahn9701]

Great info! From my experience with black oxide hardware for non-automotive applications, the rust protection is only fair on its own. Using a sealer like Cody mentions is very important to making the coating last.

[@DaveSmith-cp5kj]

Same. I've done it on some firearms and the corrosion protection is minimal.

[@emoverrette9568]

Thanks a lot. Love it. I want to do my shifter (hurst) and rods. I was going to paint them but I want it to look original since it goes to my 68 Camaro . Great tip thank you .

[@bhaggen]

@emo verrette.....I find that tossing the old rusty parts into acid from old batteries works great. In fact I just restored the rusty old hood hinge assemblies off a 65 Chevy by filling a std spray bottle with said acid & spraying them down a few times. Subsequently, after an hour, the rust washed right off. You just can't beat that old-school American or German steel

[@Ondstockz06]

Great video ! Thanks! still useful info 2023 !

[@jonvancil5547]

Thanks for this video. Im doing a Porsche on the cheap and this will definitely help!

[@makeitup3093]

Wow when that glove got near the wheel I ran

[@petermarsh4993]

Thanks for the video. I too have received a Caswell steel blackening kit but was getting highly variable results with my machined items. What I did not appreciate was the need for more aggressive surface preparation as you demonstrated with wire wheeling or abrasive blasting. That was the missing link. Fingers crossed I can get the sort of deep even black that was shown on your bolts.

[@craigrainbolt2723]

Thank you so much for this video!

[@heydonray]

Thanks for this info dude, very helpful and well done.

[@bigbraincontent]

Classic video sir! ✔ 👍

[@visionowner]

Thanks for the demo. I'll give it a shot now on some shop tooling I've made.

[@daveynipples]

love the bloopers! a must for future how to's i think. :)

[@pnwdiy2073]

Great video and easy process. And this is essentially the finishing treatment the factory used with the exception of hot oil immersion. I am doing an F body 1st gen Camaro and will begin using this process. I have been sandblasting and shooting chassis bolts with diamond clear but the factory oxide black is nicer.

[@bertkutoob]

Tim, I've had good results heating bolts to 400° F (easily achieved in the kitchen oven) and dropping them in boiled linseed oil. Once cooled, wipe off the excess and stick them back in the oven for a couple of hours. Buff them up on a cloth wheel and they come up dandy. Caveat! Get your wife's permission to use the oven...!

[@pnwdiy2073]

@@bertkutoob Great info, thanks. 10-4 on the permission. FYI - valve covers and intake manifolds fit perfectly in the top rack of the dishwasher.

[@bertkutoob]

@@pnwdiy2073 Well since you seem to have hijacked the kitchen, you can make the rules... Just to avoid confusion, the linseed oil treatment is as a sealer after going through the black oxide process and not as a substitute. I've heard that heating the object to red hot and dumping them in old motor oil produces a nice black finish but I wouldn't try it on something that needs to support a serious load (such as a wheel stud) until I learn more about the effects of this on structural strength.

[@mchapman103]

Mate, thanks for sharing. Looks simple and straight forward, let you know how we go.

[@jasonf1451]

Looks great. Here in Oz I have 144 outer perimeter nuts on my vehicle wheels to do. They are zinc plated but some of the zinc has worn off and some slight surface rust. I am hoping the chemical will bring them up consistently black and protect them. The main nuts (those holding the wheels on) are new Haltec 22mm and already black oxide. I will need to seal all of them. Looking for something better than WD40 as it will only last a week.

[@A3203503]

I was hoping the unprepped bolt went in as well, just for the curiosity factor and how it would turn out.

[@lw4santo]

@Dorifto Kun! did you use that "black oxide" solution? Or something else?

[@fxrsniper1]

It does nothing to it as he stated

[@erikrichter1026]

Great video Thanks. I just did all my fender bolts and they came out fantastic. I like using a like using a light oil as the WD - 40 did not leave as good a finished look.

[@billparsons7732]

Very nice, I'm going to start laying on the ground and looking up at bumper bolts with a flashlight to see how they compare.

[@tomharrell1954]

I make my own WD40 and call it WD 39 1/2 I put mineral spirit, acetone, and kroil mystery oil. Works better than WD 40 and leaves a oil film. Oh it’s about 1/4 the of price too!

[@dennisjump8655]

I'm going to do this on my resto. Thanks.

[@MatthewWatt-b9q]

Great work brother, ripper vid!

[@beastgirl43]

Great vid. So Zinc plating is not required first. Yellow dicromate only takes to a zinc coat so this is interesting. Nickel coat also requires a copper strike coat so this black without zinc or copper electrolysis is very cool if it truly holds up well

[@CudaCody]

Yes, to get a Yellow Dichromate finish you need a Zinc coat first, but this Black Oxide does not. It will hold up about as well as an original phosphate. You can try using a satin clear instead of the WD-40 or other oil sealer. Heard that holds up good and still has a nice original look.

[@SertEngineering]

Thx for video. Good job.

[@petermorthen]

Great video. Was just looking for better ways to clean up old bolts. Thanks.

[@bigmike2149]

Cool video! I use gun blueing solution. Not sure if this is the same thing but seems to work pretty well.

[@philf5043]

Good demo . No B/S . Keep it up . Thanks .

[@dntlss]

Awesome video,I'm gonna try it out,i work in a shop and i have access to a media blaster but once i blast the bolts not really sure what to do with them, Ive painted them before but the paint makes them thick and I'm not really down with that, id like to find something like a coating of some sorts so i guess ill try this out, I'm not looking for prettiness, just looking for something to keep the bolts from rusting,this is all done to cars that i restore for my own personal use.

[@mikebrooka9395]

Very nice to know information! I have learned that peanut oil might work better. Take care from Oklahoma Mike and Vee

[@jackrichards1863]

Thanks Mr. You're a good man to have around. I don't know where I'll get black oxide phosphate (concentrate?) since I live in a ultra rural town.

[@TheDesertsweeper]

4:40 "So this is what they look like coming out" - flashes them to the camera for .3 of a microsecond :)

[@EgradJA]

Everybody has a Pause button.

[@Good-Enuff-Garage]

@@EgradJA yeah but it's annoying to have to do that, plus sometimes it's hard to pause it in focus, where they guy could just hold them there for 3 seconds

[@heydonray]

Oh my goodness. It was plenty of time, but some people just have to complain.

[@TheDesertsweeper]

@@heydonray it was NOT plenty of time. Not on any planet. And who said I was complaining? Don't make assumptions. I was merely pointing out that this is THE moment, the whole build up, the coup de grace...from a video editing and narrative perspective, 3 or 4 seconds would have improved the delivery immensely. So I suggest YOU stop complaining and go and do something useful

[@heydonray]

@@TheDesertsweeper If it wasn’t enough time for you, then you’re comprehension is just slow. The guy did a great job with the vid and if you don’t think it was up to par then all you have to do is hit pause. Not complaining? Yeah right. Whatever. It certainly wasn’t complimentary, so go gaslight someone else.

[@jdimeo1966]

Does anyone know if you have to media blast or wire wheel the bolt first? Wondering if the bolt is paint and/or rust free, has been degreased if you can dip the bolt as is without putting it thru the abrasive step.

[@markkoons7488]

Nice presentation and useful. Thanks.

[@EgradJA]

Well done DIY video. You have a very nice workshop.

[@chriszbodula1894]

Both myself and my machinist tried the Caswell product and it’s not just bad but it’s close to useless. If you decide to try/buy it make sure the give you a money back guarantee.

[@RedRupert64]

That surface will corrode pretty quickly. It would be better to zinc plate them and used some blackener in the process to finish up with black zinc.

[@MidnightWulfie]

Great video, thank you! Does this method work on alloys, like a fuel tap on a motorcycle for example? Not really sure what type of metal they are, some sort of antimony alloy I think.

[@MichaelBrown-de7vf]

What if I have everything needed except compressed air (I'm rebuilding a vehicle so its hundreds of screws and bolts)

[@jaycobie]

"You can do at home or anywhere" "Ok now lets sandblast it" Yes, because everyone has a sandblaster at home

[@BrentHasty]

You should have also done a rusty bolt without any wire Wheeling or treatment to remove rust

[@foggymtnbreakdown]

I think that a black oxide coating and a phosphate coating are two different things. I don't think you are making a "black oxide phosphate" coating. Even the Caswell bottle in the video just shows "black oxide" on the label. You don't necessarily need air to de-dust your items. A distilled water rinse might work even better. Shake the excess water off. The distilled water won't matter because you are putting the bolts in a water-based solution from Caswell.

[@buildit1091]

Great video! One question, Could I wipe/spray on the oxide? I'm trying to blacken metal table frame. Thanks,

[@CudaCody]

You bring up a good question about other application techniques. I've tried a couple different ways to apply it and they've worked good. For example, when I want a factory stamped steel look (say on kick down linkage), I wire wheel the linkage and wipe the Black Oxide on with a grey scotch bright pad (as even as possible). Since I don't want a very black look it only takes a few seconds for it to give me the look I want. In your case (spraying the solution on to a metal table frame) I think it would work good and you'll just need to watch the amount of time you leave it on to get the look you want. The key is to get it applied evenly. Try using a scotch bright pad to evenly spread it around after you mist it on with spray bottle. Try wiping the solution constantly so you don't get an uneven look. The Key is not to get drips because they will etch the metal and you'll see them. Practice with a couple test pieces before doing your table to see how it turns out, but I'm guessing you're going to love the way it looks. You can clear coat the table frame too instead of oil and it will seal up the black oxide too. Good luck! :)

Clear explenation and with enthousiasm

[@shooter7a]

Black Oxide and Phosphate are not the same. Black oxide is a conversion coating that forms a protective surface by reacting chemically with the iron in the metal. Black phosphate is created by dipping parts in phosphoric acid and phosphate salts, which creates a crystalline structure on the surface.

[@DontCloudMe]

I've been looking for something like this to finish my cleaned up parts. I was going to try my hand at chroming but once I saw the terrifying life-threatening process, I decided that a rusty part was more acceptable. But this takes less than 5 minutes and the gaseous vapors wont cause me to bleed from the ears and grow gills.

[@donaldb3628]

Rusty parts are NEVER acceptable except to amatuers!

[@echochildus2441]

I'll stick with blueing the metal with a torch and oil quench. nice video though.

[@LedZeppelin13k7]

I clicked on this video and when I saw all the stuff on the table to do this process I said "nah" lol

[@DdgeShelby]

You're overthinking it. All you need is the black oxide concentrate and some distilled water. I made this video. kzbin.info/www/bejne/gnfan4iip71jn9U

You are an idiot. The stuff on the table is showing you all the other things you DON'T need to use for the process. LOL

[@deangaryjames]

Same here, be cheaper to buy new bolts

[@paulandreotti1639]

@Reno Simpson $30 to cover *at least 750 sqft* of surface area VS buying the equivalent in new hardware while disposing of hardware you already posess. Honestly, the only draw back to this method is using a wire wheel because it's tedious.

[@txman951]

Awesome, thank you. Just what I'm looking for.

[@paintnfaith7256]

Love this vid, thank you very much and would this work on aluminum? Ive been fabricating aluminum tattoo machine frames and hate powder coating them as I can't heat treat aluminum as I do with steel frames. Any advice would be great. Thank you again sir.

[@keithstoneholdmystones1259]

Cuba Cody do they offer a different color selection of the oxide concentrate? I'm trying to figure out what route to take anodize with electricity or go with the oxide concentrate, what are your thoughts on the two different processes? I appreciate your time thank you!

[@CudaCody]

Anodizing with electricity should be much stronger and give you a better result, but it normally costs more and requires more equipment.

[@carllove3705]

That is nice. Would that work for a carbon steel knife?

[@jamesn.4892]

Will they be rust resistant? Better than Zinc or nickel plating? I'm contemplating this for a bunch of golf cart hardware.

[@codyreich]

You would be best off using Zinc or Nickel. Or just you stainless.

[@aaronmills7731]

Great Video brother

[@johnnys3160]

Is this better than using Super Blue or Heating with Oil?

[@thakurboys5962]

I think and blaster is the expensive one in this whole process.

[@vantatilfly]

Nice trick. I have this grab bar at the back of a motorcycle and i think it's magnesium or aluminum. Will it work on that?

[@Mech.Masters]

When a casting is black oxidized does it look brownish ?

[@FloridaBandit99]

Does this coating hold up as well as the "cooked" on coatings? Thanks for the helpful video.

[@DdgeShelby]

Powder coating will add thickness to the nut/bolt causing the size to not be exact. This stuff holds up great.

[@Nperez1986]

Great vid? Couldn't we also blue them with boiling oil? I do it when restoring older rifles...

[@ianlim7896]

Does this work with all metal types eg stainless steel, cast iron, etc? Thanks!

[@CudaCody]

Hello Ian, this will not work on Stainless. But find a piece of cast iron and do some tests first. You should be able to find a way to make it work good on Cast Iron. Try using a spray bottle on large cast iron parts and maybe even a shorter period of time. The key will be to get it applied evenly and wash it off before it sits on there to long. Good luck.

[@ianlim7896]

Thanks mate. What would you recommend for Stainless Steel (to have similar effect)?

[@Fosgen]

Want easy and lasting coat? Strip to bare metal in muriatic acid or wire wheel, degrease, clear coat, dry, install. Mix 10 parts petrol, 3 parts paraffin, 1 parts lithium wax. Warm on water bath, apply with brush on hardware. Enjoy it completely rust free for next 1 to 3 years, depends on climate.

[@gonzalosanchezsanchez2707]

excellent video, very illustrative, but I do not know why, the product works better on Chevy screws and nuts. XD

[@tomsmith7747]

Nice video but, 9 oz. of water and 1 oz. of chemical is a 9:1 ratio. You would need 10 oz. of water and 1 oz. of chemical to produce a 10:1 ratio.

[@Slugeinstein]

if you pause the video in the sec 0:37 the label in the bottle says 9:1 ratio, as well he mentioned the same 9:1 ratio

[@Platingisfun]

Insta Blak 333 is used at 10% by volume. For some people is easier to say 9 parts of water and 1 part of blackening solution or 9:1 ratio.

[@holliwood3226]

is this the same as phosphoric acid treatment?

[@visionowner]

No. In the end, the black oxide is a slightly inferfior finish that acts as a "tooth" for sealants to bond. Phosphoric acid finish is akin to a sacrificial anode coating. i.e. it is the less noble of the two and therefore corrosion will take to it before the base metal it is coating. The big upside to this or other cold-bluing methods is that you don't have to deal with the Haz-Mat byproduct nearly so much. In some locales, disposing of phosphoric acid is a real headache whereas cold bluing or black oxidizing is relatively quick, inexpensive and less toxic to handle. Phosphoric acid can also attack a bit of thin material that you might be trying to preserve. I wouldn't want to use it on thread restoration, but then again, re-using old, torqued fasteners is not a very sound practice from an engineering standpoint.

[@upsidedowndog1256]

Looks good. How long does it protect from rust?

[@allmycarsisbroke]

Shouldn't you be using distilled water, not tap water, to rinse your parts after pulling them out of the blackener concentrate? If you haven't yet protected them with oil/sealer, I would think you are introducing minerals to catalyze corrosion.
