Powder coating bolts

[Guest]

Has anyone got powder coating on some bolts and it last after wrenching?

Looking at doing the bolts on my Stator and Generator cover in teal or black.

Changing screws on Carb covers to bolts and do them teal or black as well for accents.

Not sure if will hold up after wrenching them in.

It's pretty tough, it might work if you use a six point socket that fits well and be careful tightening then up.
I haven't done bolts, but I have done bash plates on dirt bikes, even after landing hard on big rocks the surface is barely damaged.
Have drop tested a few parts too, they usually don't even get scratched.

I have done some of the larger bolts on an engine and frame. The secret is to have the guy doing the powder coating to NOT do the thread; only the head. It will hold up on these type bolts decently because they don't get a wrench or socket on them often and so the coating won't tend to crack. If you do smaller, the coating will likely be fine if you just do the heads. And teal? Really hehe

I think you'd be better off with anodised ones - PC is not really going to work for a bolt head.

Oh, I just assumed you were doing the powder coating yourself. I have to do a couple bash plates and such the next few days, I'll do some bolt heads too and see how it does.
I think it will be fine on the ones that don't get removed all the time like axle nuts, especially the ones that don't get torqued all that tight. Standby a few days, I'll find out.

Sorry, I don't have any teal!

Cool, Thanks.


Looking at Valve cover bolts in teal, Generator cover bolts in teal or black and Stator cover bolts in teal or black.

Any update/ luck?

No, haven't had a chance to even look at any powdercoating.

I don't know if this will help, but i have a few bolts on my suburban that were powder coated black. The EGR block off plate i got had the allen head bolts powder coated and other than making it a tighter fit to get the bit in, I have recklessly attacked those bolts and not chipped any paint off and they sit on top of a very hot running SBC 350. Only heads up i can give you, buy some new tools that aren't dirty and all marred up and you should be fine. Just make sure that they are powdered on the head only(not the threads or the under side that makes contact with the surface its bolted too-you will get a false torque setting otherwise) and it is a thin coat on the tool surface so you don't have to sand anything to get the tool to fit.
