Lug Nut Bolts

[Sunshine521]

Hey all! I have a 69 521 in need of lug nut bolts. I had bought some off of eBay and they were not the right ones(they were too big) any suggestions on where I might find some? I have 1 bolt snapped on each wheel and want to replace ASAP. Thanks!

The thread on a stock 521 lug nut is 7/16-20.  I am not sure of the length.

I think he’s talking about the studs.

 

I have a whole set sitting on my work bench, since I replaced all mine to fit aluminum wheels.

 

How many do you want and where are you located?

Being in the bay area, you should not have a hard time finding a Datsun guy to help you figure this out.

 

Or you could simply remove one and take it to your local NAPA to have it cross referenced into a Dorman part number. Where in thje bay area are you? If you're anywhere near Concord, Monument Auto Parts is the best, or at least they used to be. I don't live in the bay area anymore, but when I did, they were the best.

Napa can look up the proper studs.

I just recently moved out to Manteca in the valley but commute everyday into the Bay Area so it’s not a problem to stop by a shop in the bay to get the studs if they have them. I need 5 or 6 studs total.

I don’t think the factory studs are available anymore. Dorman makes studs that work, but they need to be modified to fit.

 

If you PM me your address, I’ll drop some in the mail for you.

Dorman P/N 610-157. They’re longer than stock, but the right thread size. If you want them shorter, you could cut them.

 

You have to angle grind a flat on one side of the head so that it fits the back side of the hubs. I used a lug nut flipped over with some grease on it, and an impact wrench to pull them in.

Nice job Mainer. Part numbers are awesome.
