I am getting ready to mount my Bison 8" 3 jaw on its backing plate
and cannot find a spec on torque for the bolts that hold it to the
backplate. I have looked in the manual that came with it and no luck.

Since this is a common chuck that most folks have I was hoping
someone could give me an idea of what to torque the bolts to. I will
also put on some blue loctite so the do not move. Any help greatly
appreciated.

Thanks, Steve

Standard torques for bolts have Socket Head Cap Screws at 16, 33, 54 ft lbs
for 1/4, 5/16, 3/8" That is a good starting point and adjust down from
there. I would not use the locktite unless I confirmed in use that the
bolts were loosening.

Fine thread torques will be lower for the same diameter bolt because of
the smaller pitch of the thread.
