It is remarkable how much we all learn by actually building our own cars. Nice looking brackets & chassis!Thanks to Neil for the advice, I did not know that. The polished frame with the red brackets looks awesome!!!
Hey Neil, you seem to know a lot about this, but I reached out to the bolt manufacturer to check about the baking process to eliminate the Hydrogen Embrittlement risk from electroplating.I wouldn't use chrome bolts. Chrome plating imparts brittleness in high strength alloy fasteners. Use stainless, titanium or A256 alloy bolts instead. AN/NAS/MS fasteners are excellent. SPS makes good commercial fasteners, too.
Also, your bolts don't appear to be long enough (based on the pictures, can't tell if they are torqued down or not). You should have a minimum of 1 thread protruding past the nut, and 2-3 threads is recommended. The nyloc part of the nut in your picture is not being engaged.

It is good that they recognized the potential problem but baking out hydrogen successfully requires detailed knowledge of the metallurgy of the alloy. An alternative to chrome plating is to use an "electroless nickel" process.Hey Neil, you seem to know a lot about this, but I reached out to the bolt manufacturer to check about the baking process to eliminate the Hydrogen Embrittlement risk from electroplating.
This was their response:
Chrome is just a plating or a coating, just like zinc or phosphate. Hydrogen Embrittlement is an issue in electroplating, which is mitigated by baking appropriately. Any plater worth their salt simply includes the baking in the plating process, as ours does. Same applies to chrome platers, if there is an electroplating element to that particular process. We chrome plate bolts for all kinds of high-strength applications. Again, our process is called“Polish, bright chrome, and bake.”
Not sure if this satisfies me, but it is more data than I had before. I have learned a lot about the process because of your post, thanks!
Yes, I grew up in my dad's shop building customs and street rods. We went to many car shows and I would like my son to experience what it takes to get a car ready to show. We will drive the car to the shows and back, yes, I know it is a lot of work and you have to clean and polish. But that is just busy work.Gorgeous - Are you just building it for show?
Yup, I know, but I am trying to make something look "cool". A couple of bolts and you will remove it from the engine.that will be a nightmare to keep clean and I am not sure what it achieves, you can still see the engine and parts underneath
