X-treme Axle Nut

I have a bike that is much like an XB-508.

I have lost the axle nuts

I have bought a number of nuts trying to find the right size but they always seem too big, small or wrong threads.

I think XB-500, 508 and 600 would all have the same part.

Does anybody know the exact specification of the nut required?

Re: X-treme Axle Nut

It really might help if you posted the brand and model scooter you have. Or, alternately, you might look for a "scooterparts" ploace on line, and talk with them, maybe they can source the right part for you. Another option would be make a partial mold of your axle shaft with clay or something, let it harden good, and take that to the hardware store with you. Should be a lot easier than carrying the whole wheel in, but that is an option too, if its a front wheel.

There are a LOT of scooters "much like an XB-508." My XB600, I'm pretty sure, has different attachment hardware than the 508:

"XB-600 Axle tips

I'd take the motor and axle to a machinist to get it measured. You could also measure it yourself with a micrometer and a metric thread pich gage.

Re: X-treme Axle Nut

Maybe these guys could help...
"or call us at 1-888-539-8318 or 1-604-625-3888", from the Kaishan page, or, use the dealer list to find a dealer with a toll free number. surely at least one of the dealers could tell ya the specs for what you need, or sell ya the parts. If they wont help, I dont need to buy their bike.

Re: X-treme Axle Nut

Just a word, of course butdid you think of just taking your wheel assy off the bike and taking it down to your hardware store. The front wheel has two bolts some washers and the drum brake or disc just slides off. Your back wheel assy.
is of course a little harder but I've taken my back wheel assyof about 5-6 times already since sept 2009.
And plus you'd have it right away and you know right away it fits.
Not to be cocky or anything but the time it took me to read this thread and write this I'd be coming home from the store with the right size bolt.
SORRY!

PS the hardest part you'll have is carefully unhooking the connector wires from it's housing to be able to slip the wires through the bolt, that's if it's the power side of the rear hub motor.

Re: X-treme Axle Nut

I sorta did that. Nothing in the hardware store stock fits. "too big, small or wrong threads."

If I don't hear back from Kaishan, my next step is a specialty bolt store: www.boltsupply.com

From their catalogue I have learned that there might be three different choices of thread count in this size metric bolt.

Thread gage

Thread gauges are not expensive, and they will indicate precisely what pitch the threads need to be. In turn, a fairly inexpensive caliper will measure the major diameter of the axle. With those two numbers, you should be able to find the nut you need.

or, as I pointed out, if you don't trust your own measurements, a machinist will do it in a minute or so.

We don't have to ask China for everything...

Re: X-treme Axle Nut

Hee hee, that was an image from Google Images. I've got a matched pair of Starret gauges, SAE and Metric, in their original boxes. And they're NOT for sale! They're an important part of my lathe.

For mere users, not collectors, they aren't very expensive.
