Lock Nut Replacements
 

Somehow the lock nut on the front wheel of my b4 fell off after I crashed.
As I can not longer find it I need to replace it as a three wheeled car is just not the same.

I could replace it with the official part 6222 labelled "4-40 or 5-40 Black nylon self threading locknuts" however I was wondering was it worth changing to aluminium e.g. something like losi 4-40 aluminium low profile locknuts? is there any point and will they fit.

If someone could also explain what it mean by 4-40 or 5-40 and which I will need?

Thanks

Hey,

4-40 / 5-40 refer to the size of the thread.

The front axles on the b4, the ones that need a nut to keep the wheel on are a 5-40 thread. The 6222 nuts are nylon and the axle will cut a thread into them.
Part number 6629 are Associated 5-40 lock nuts.The 6222 nuts are good enough for the front wheels and are what most people use. Just change them every so often.

Any from Nortech to be recommended?

Im sure graham from nortech could get some 5-40 size thread nuts in stock but id doubt he has any the moment because it's not a size used very often!

Worth pm'ing him :D
