Hello all,
Can the brain's trust tell me what or what type of wheel nuts will fit Momo Vega's to an Alfetta GTV.
On my other wheels, I use the 19mm nuts with the attached (or fused) "washer" (if you understand what I mean).  If I use these on the Momo's, the "washer" part is too wide and wouldn't fit and tighten down on the stud.

Have I got it wrong or am I using the wrong nuts.

I know Paul Newby has Momo's on his GT, maybe he can chime in.

Thanks Rob,


The "washer" is attached or part of the nut.  Here is pic of the nut I am using. 
I was thinking of the acorn type but just weary of the taper biting and gouging out the stud hole, have seen it before.
Hence why the washer type nut on my other wheels, where the taper of the nut fits into the taper of the wheel and the washer part press down on the wheel, if you understand what I mean.

Any ideas will be great.

Here is a pic of the nut on the Momo, I didn't have a hub hanging around but you get the idea.
So I need a different nut but I don't want just a taper acorn as I think the taper will wear on the stud hole.

Please advice.

Thanks
Neil

You think I can machine down the washer part a mm or so to fit pass that inner whatever you call it edge towards the hub hole.  But not ideal as if I lost a nut at the track and trying to find one by stealing from another Alfetta donor car (spectator's) will be a problem.

Neil, you can nip off that small amount with a disk/belt sander or if it is for the race car, you need to get new nuts anyway. Those nuts are from the standard campys

Hi Neil

The washer will come off.

Put the wheel nut in a vice with the threaded section up,and the vice supporting the washer.
Thread an old stud in the wheel nut and bang down,and the washer will come off the wheelnut.
You could also use a suitable punch with the same effect
The wheel nut + washer was used to hold the Mexican Hat hub cap in place on 105s and Alfettas.
Nothing wrong with your wheel nuts.
You can buy new ones if you like.
All my Momo wheels are attached using these wheel nuts,including my Black 75.
Any doubts or problems,,you have my number.

Some others have used 17mm nuts on these wheels so a socket will fit easier.
Because the wheel nut you are using is longer,you should not have a problem,and no expense of new nuts.

Hope to see a few of you at the East Coast Challenge next month.

Neil,

Technically with CAMS you need open end set of nuts anyway.

This is what I bought recently for may group S car.

Thanks Rob,
It fooled me, had me wondering all day at work, so went down to Angelo after work and got one and knocked it out.  You learn something everyday.
So it will be usable but I would prefer a nut with a bigger taper.  So will go with HMD's suggestion, perhaps, we will see, no hurry.  I will try the originals and have a play, might save a few bucks and buy unnecessary stuff.


What is the reasoning with open end wheel nuts for racing?


Cheers buddies.

The reasoning for an open ended nut is to show the stud and show how many threads of the studs are holding the nut.
A scrutineer can ask a competitor to remove a nut or 2 etc,to show how many  threads,if it is a closed nut.

Niel..you can also cut the end of that nut to show the stud.
I prefer these nuts as they have more threads than normal.
But then again,,some competitors use spacers between the wheel and hub,which makes less thread.

Neil - I have a old ice cream container full of wheel nuts in the garage.  You're welcome to whatever you want. There's plenty of tapered open nuts as I recall.

I've only just seen this thread now ...  :)

I started off using original nuts like the ones you described with the washers removed.

When I was told I needed to use open nuts, I cut off the end of the original nuts. However after a while the nut ends would discolour and go rusty - not a great look.

I ended up buying a new set of nuts from Nice Products in Sydney. I can't remember the specifications (I'm at work), but they weren't expensive and gave me piece of mind.

I think I still have my old nuts in an ice cream container too...  :D

Thanks Paul,
I have tried a few different style nuts and seems to conclude that I need 17mm acorns.  I am hoping the taper is then narrow enough to fit pass the inner part of the wheel as the original 19mm hits it and the taper interferes with the wheel so will not clamp down.  Unless as suggested I machine out the wheel.


Any more insight will be great.
