[Michael MacLean]

 Certainly sounds like logical thinking.  Just wonder how effective it is an reality, but I will install it that way!Mike M

The wheel nuts are handed so that the inertial force of the nut in motion will tend to tighten the nut against the wheel center.
One thing I noticed while serving in the Army reserve was that the wheel nuts on all of our heavy equipment is also handed by the side of the vehicle they are located on. However in true bureaucratic fashion all of the left handed fasteners are located on the left side of the vehicle and all of the right handed fasteners are located on the right side of the vehicle. Thus proving that the inertial forces they are designed to counteract are not great enough to affect their position. I can see a lot of money wasted in the logistics of installation and stocking of both left and right hand fasteners for most military equipment...

Subject: Re: [Healeys] Rear Hub Spline Extensions Thanks Mike.  I didn't see that coming.  So, does the tightening physics of thread direction only apply to the hub extensions?  Easy to make a serious mistake here.  Thanks again.Mike M

Hi Mike, No Mike, just to keep things interesting the threads on the extensions are the opposite to the bearing nuts ...so:
Bearing nutsLHS left hand thread.RHS right hand thread
Wire wheel adaptors (Spinners)LHS right hand threadRHS left hand thread

I am finishing up the rear axle for my BN2 by installing the hubs and hub extensions.  Am I correct in assuming that the hub extension threads are "handed" in the same direction as the hub nuts?  Mike MacLean_______________________________________________
