    Rear Hub Nuts

    I am going to treat myself to new tyres, wheels, front and back hubs. I want to replace the studs on the front hubs and the nuts on the rear hubs in the process. The normal suppliers carry them but they seem pricey for nuts and bolts. Does anyone have another source or know the specs so I can look for them. I have a BT7. I think someone covered this some time ago but I have no skill with the forum search engine.

    Re: Rear Hub Nuts

    I had bought them for a reasonable price from Scuderia Silva in Portland, OR. Doesn't seem to have a website. Phone 503-380-7756.

    For 10, from AHspares, $41.90 + ship:

    Moss: $47.90 + ship

    Added:
    All the studs are 7/16-20. I believe your disc front studs are 2" long. Dorman sells these in a 10-pack:

    The fronts use regular (non-lug) nuts and washers. You could substitute all-steel locknuts.

    Speed sources like JEGS sell high-quality US-made 7/16-20 lug nuts, which could be used on the rear with orange loctite. Make sure the bevel angle is the same.

    Edit: I have a loaner rear hub with 2" studs; my own car has 2-1/4" studs. IMO 2" is the minimum length on the back. My previous post (deleted) showed 1-3/4" studs which on the back at least are too short.

    Re: Rear Hub Nuts

    The rear nuts that hold the splined hub in place have a ring on the end that acts as a locking mechanism. Loctite couldn't hurt, especially if the nuts are reused. Plain conical lug nuts are common for steel wheels where the springiness of the steel keeps pressure on the lugs. I don't think the splined hub would act the same way. If Steve has had positive results with the loctite, then you have a less costly option.

    Re: Rear Hub Nuts

    Steve, do you have any idea how much performance gain I can expect with "drag race" lug nuts. Quicker off the line? Higher top end speed? No matter, at this price, it's worth a shot..

    Re: Rear Hub Nuts

    The bevel angle is the issue. I did a write up on this a longtime ago. The bevel on the commonly available new hubs from the usual suppliers is not the same as the originals. I found that the original-type lug nuts with the “built-in” lock washer did not grip the replacement hub and and did not fit properly. The dorman nuts did fit properly as the bevels matched up. I never had a problem with the nuts loosening once I switched to the dormans. I suppose if you still have the original hubs you would want to stick with the original-type nuts, but if you still have the original hubs the threads are probably suspect. Again, it is all in the matching bevel as Steve pointed out. Lin

    Rob - the details on the Moroso lug nut page list their drag-race certification. Strength of nuts and studs is an issue.

    Lin - Yesterday when I removed one of the stock-type nuts with the spring, I noticed it wasn't very tight. I have replacement hubs from 2001 or so and had replaced the original-style lug nuts 7 or 8 years ago.

    Re: Rear Hub Nuts

    Just removed the other 4 spring-type lug nuts - they weren't tight at all. Any more loosening and the hub would have started to rattle. My hubs, from the late Hemphill's Healey Haven, are definitely 60 degree bevel.

    IMO the Moroso lug nuts are overkill.

    Lin - going with the Dorman lug nuts and loctite. 25-price:

    Steve, I have used the very same Dormans for 7-8 years with no loosening at all.

    Re: Rear Hub Nuts

    If Steve and Lin recommend the Doman nuts, only Randy Forbes's is missing to make this a indisputable decision..... Since Randy's under the weather, I'm going with them.

    Re: Rear Hub Nuts

    Well, just to restate, what is important and what makes one nut right and another one not, is that the conical seat of the hub needs to match up with the bevel of the nut. Somewhere along the line the hubs changed from original and at least with the ones I have the 60 degree bevel matches perfectly.

    Installed the Dorman lug nuts with Permatex Orange threadlocker. 1/2" to spare on my 2-1/4" studs.
