Dennis, one thing we were taught in aviation mechanic school that I
think might apply here is - if a specified torque value nor a standard
torque value is not available, then finger-tight-plus-a quarter-turn was
the principle applied. None of this "tighten 'til you can't turn it no
'mo " stuff. A variant  of that might be to "snug it up - then a quarter
turn" where screw clamps are concerned. I think that is safe enough.
