[Healeys] [SUSPECTED SPAM] Re: torque wrench

[Michael Salter]

Way back in the "olden days" when I was doing my aircraft engine fitter
training we were given a graphic demonstration of just how varied the
clamping force that a nut tightened using an accurately calibrated torque
wrench could be.
Forget the 2 - 5% inaccuracy of the wrench and concentrate on clean, unworn
and correctly formed threads, proper countersinking at the top of stud
threads, sufficient thread below the nut, correct lubrication of the
threads, perfectly straight studs, serrated washers or soft washer
materials, correct tightening sequence etc etc..
When you see how those factors can affect the clamping forces the accuracy
of the torque wrench, which BTW in the services had to be checked daily,
you realize that the torque wrench is only a part of the equation!!
