VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 29 wheel lug bolts

Hi Guys,
I would like to replace all the lug bolts and nuts on my 29 Chevy's solid/artillery wheels.
FS shows(or that is all I can find) only the modern bolts with round heads and splines.
Any suggestions or pointers will be much appreciated.

Hello Floats,
If you can find out what the part numbers of the lug nuts/bolts are, you may be able to track down a replacement source. Try to find the info going to 'old online chevy manuals' and look through the "1929 thru 32 Master Parts Price List Manual". That may be of some help to you.

TKS Harry,
I'll have a look.

Hi Floats.
I purchased the lug bolts FS-631 from FS. They looked exactly like the old ones except they are slightly longer (1/8th. inch aprox.) I asked FS if this would work and they assured me they would. The nuts #354800 also look like the original. I did assemble one wheel and the bolts seem to work OK, however I am not certain if the nut bottoms out before the wheel is clamped securely. I may shorten the lugs a little. I have been unable to find the hub bolts, but mine are OK. I will probably replace the nuts. I want to see if a 7/16-20 heavy hex nut is the same dimensions.

The acorn lug nuts, part number 354800, are the correct lug nuts for the 1929 and 1930 disc wheels and they are also the correct lug nuts for the 1930 wire wheels as well.

Hi Gents,
I must apologise. I was using the wrong terminology. I am looking for wheel rim bolts, the four bolts holding the outer rim and tire on the solid wheel.
The bolt is about 3 inches long and the head looks like a base ball cap with the peak turned up. Sorry I cant post a picture.

Always be very specific with your question othewise you will get answers to your question that does not apply...like those above.

TKS JD,
My mind was elswhere(probably in a gutter somewhere) and I did not even give my request a second thought.
However, now that we know what we are talking about, do you have any pointers for the bolts I require?

You might want to try Gary Wallace. http://www.20schevyparts.com/

Good luck!

TKS, what are those bolts called?

Demountable rim bolt.

Thank you Sir

You bet.

I meant to say "rim bolts". I couldn't find new ones. Used ones are on EBAY sometimes, however, most of them are pretty rough.
I am wondering how much a machine shop with CNC programing would charge to fabricate new bolts. The nuts do measure the same as a 7/16-20 heavy hex.
You could try posting on the parts wanted section on this site.

I think I would try a local machine shop to fabricate.

It looks like a baseball cap with the peak turned up. I suppose one could turn a cup to hold the ball stable, then cut a quarter of the cup away. Somehow position the cup and bolt vertically in a press, then bend the peak up by using hydraulic pressure.
Thanks for the suggestions gents. I put a wanted add out here in South Africa, lets see what comes up.

Take a threaded bolt same length and thread size. Have the machine shop add welded material to the bolt head to make "ball cap" shape. Then use a die grinder for detail. You could match it pretty close. Best of luck.

Welding and shaping the head won't help. You need the oval shoulder underneath the head that is supposed to be peened once installed in the rim to 1. Keep it in place and 2. Keep the rim bolt from turning when you install or remove the rim.

I thought Restoration Supply in CA carried those bolts but now I can't find them in their catalog. Those same bolts with the oval section under the head are still used on the victaulic couplings we use in the fire sprinkler industry. Seems like something similar was listed in one of the larger Lucas, or Coker tire catalogs some time back.
