Stop trying to blind me with science Terry.  I meant that generally the 
pins had less torque than I would like, but I did not measure the 
torque.  Two or three were loose enough to "instantaneously" move back a 
substantial amount when I put the lever on them. I hammered them further 
in and they gripped.

With regard to "IMHO, either the pin turns on it's own or it doesn't.".  
What timescale and amount of degrees or fractions of a degree are you 
talking about for the turning (if we are to be in measuring mode)?  Are 
you talking about a hundredth of a degree in six months, or 30 degrees 
in a quarter of a second?

Best regards,

David.
