1953 body bolt kit
 

does anyone make a body bolt kit in black oxide? i can find plenty of stainless kits but not in the black oxide.

Re: 1953 body bolt kit
 

Most black oxide bolts that I know of are grade 8 bolts. In fact a quick check shows that it is pretty well an indicator of the fastener being grade 8. That is why you don't see black Oxide bolt kits.

A search shows that at lest one vendor sells Grade 2 black oxide fasteners though and Grade 2 is all that one needs for body bolts.
Here is one https://www.mutualscrew.com/product/...andV7E5_hSvckI

The problem there is that they will probably only sell in bulk lots by the box.

YMMV but the black oxide bolts I used to fasten wire looms under hood and a few other places looked great until they all rusted. Which they did quickly and with little provocation.

A costly, name brand sealed box from a reputable industrial supplier too.

Re: 1953 body bolt kit
 

black oxide is gonna rust sooner or later unless it is oiled, which will attract dust and look messy as well. plated, painted, chromed, brass or stainless is the alternative. be aware there are different grades of stainless and the lesser grades will also rust. stainless is not as strong as a regular bolt. any fastener that is installed permanently should be oiled or loctited on the threads. stainless will gall easily so they will require lube on the threads and also should be installed by hand instead of with a power tool. the speed of the power tool heats up the fastener from friction and can cause galling where a "sister" fastener installed by hand in the same place would not gall

Stainless fasteners on a truck or car are purely for appearance and should not be put in any place requiring critical strength. Great for truck bed or cab fasteners if you like the look.

I bought thousands of stainless bolts (not polished) for the fruit juice/apple sauce plant I worked in for 7 years. A lot of then went where they were in contact with apple juice and were were were washed down with some pretty strong soap solution every day and were the pits for the guys to take apart and usually ended up in the scrap bin when they got taken off and were replaced. I don't think I ever bought a can of anti seize as it might contaminate the food. I bought Chip brushes in various widths by the case for the same reason. When they painted the mild steel equipment we didn't want any sort of brush cleaner in the plant. Use the cheap brush once and when done you let it dry and threw it away.

I find I have to rethread stainless fasteners before use or there is a high risk of galling, even to the point of twisting off before they pull tight.

Re: 1953 body bolt kit
 

there are different grades of thread fitment or "tightness" between the bolt and the nut, no matter the metal used for the fastener. galvanized fasteners even have a different thread than a standard fastener, eg, a 1/4" galvanized fastener bolt doesn't fit a non galvanized fastener nut

Re: 1953 body bolt kit
 

some industrial users have a pvd coating applied to the fasteners before assembly. physical vapour coating. prolly not gonna be cheap. just info.
I know a fella who rebuilds VW Beetles. he meticulously paints the heads of the fasteners, then after install he touches up the scratches atc from the wrenches used to assemble. thats a lot of work!

Re: 1953 body bolt kit
 

If you want rusty nuts, use black oxide. They look great when new as seen here but when the owner doesn't keep it clean, and sometimes despite best efforts, they get rusty. It just happens.

Re: 1953 body bolt kit
 

Rusty nuts? I think there's a pill for that. ;)

schovil, nice tidy work you do.

Re: 1953 body bolt kit
 

That must be a Canadian thing because in the US they positively do unless you do not have the correct thread pitch.
I've got a bag with about 5 lbs of black 1/4 x 3/4 bolts out in the garage with no nuts and have used plated nuts on every one of them that I have used.

Currently:
SAE threads = US fine threads.
USS threads + US course threads

More pitches of metric threads than one can count. Having German, US built Japanese spec and now the HHR built in Mexico you cannot

Metric.
There you find that European, Asian and US made vehicles all have slightly different thread pitches on their fasteners. The bolt that you take out of your 2008 HHR might not fit your 2002 VW Passat even though by eyeball they look the same and neither works in the 1992 Toyoto Corolla out back that you went out and took bolts out of to use on one of the other ones.

Re: 1953 body bolt kit
 

I can tell you for sure that a galvanized bolt will not accept a regular nut or a standard plated nut, only a galvanized nut works.
here is a link to poertland bolt that explains it

boardog, have you decided what to use for fasteners?

Re: 1953 body bolt kit
 

Well I'll have to back up on that one, In all my years I have never had cause to buy a galvanized bolt or nut. There may be some in some stuff that my mom's long time companion had that I have some of and there is more down at her place to be sorted through. He worked for Pacific Power and light for years and was a truck driver for them.

My bad for not stopping and researching the subject.
