Force transmitted along the helix of a thread

[deepaknatraj]

How do I find the force acting on the helix of a thread.

Say if I'm using a torque wrench to tighten a nut and compress a gasket between nut and a mating piece and give 100 ft.lbs of torque how much of it will be available on the helix of the thread (say a helix angle of 0.67 degrees). Assumption would be no friction.

Can someone help me with this calculation?

Thanks

Sorry. This is not a HW and I'm not in school anymore. Just trying to figure out a problem at work.

Thanks
