So I purchased a Fox Kabolt 15mm Axle for my rigid 29er fork on my IP-256. I didn't think I would have such a problem finding an aluminum nut 14x1.5. The nut that came with my 15mm axle from www.xmiplay.com doesn't fit. Does anyone have an idea were I can get an aluminum nut that is 14x1.5?
Thanks!!

Fastenal would be where I would start.

Nothing close on that site. The steel ones weigh more than the axle
I cant believe I cant find one :o

It might be worth calling. They don't list everything they carry.
Not sure of who else.

You'll need to have one made. I am very doubtful you will find one off-the-self.
I made my own a while back. Any semi-competent machinist can knock a couple out for you. But you'll probably end up paying $20-30. :-\
If you can't find a machinist, I can speak with my brother-in-law and see if he can help.

I found some titanium ones on ebay!! Not sure on the weight though. The aluminum nut on my ip265 is less than 8 grams. I am still happy to have something to try that is not steel (49grams).
I will still be looking for a aluminum nut but now I am not in such a rush.
Thanks for the idea Vipassana. My wife just quit as GM of a aerospace machine shop :'(. She has a lot of connections with shops that could do the work. I just thought I would be able to find something easily, WRONG.

Titanium will be real close to lighter than aluminum. And alot stronger.

Assuming comparable geometry of the nut, aluminum would be the lightest, with a density of 2.74 g/cm^3, titanium is 4.5 g/cm^3 - 66% heavier, and steel is 7.6 g/cm^3. Just make sure you don't get it made out of osmium, 22.57, or double that of lead!

Good to know! I found a steel nut at work and it was 10g more than the whole 15mm axle. I should have the titanium nut in a few days, I will weigh it and let you know. The aluminum nut that is on now is only 5 grams.

If you want a really light metal part, go with beryllium. However, beryllium gives off toxic fumes when it is machined so stick with the aluminum.

Considering that's such a large thread, you could probably get away from having the part machined in Delrin or a comparable high-strength plastic. ^_^
