What do you need to know about tightening torques?
With most fixings, where we are fixing something to a base material, what we need to do is to generate a clamping force through the fixture. As long as that clamping force is greater than the applied load the fixture will not move.
What should the torque of screws be when mounting optics?
when mounting optics with an integrated rail (SR rail, ZM/VM rail), the recommended torque value of screw tightening is 40 in/lbs or 4.52 Nm. If these tools are not used when mounting the optics and tightening the screws, two things can happen that greatly affect the precision, reliability and life span of the optics:

What should the torque be on a torque table?
Torque specifications are shown either as an exact figure, or a specific range. Follow any special instructions or multi-step directions carefully to assure correct final torque. There may be different specifications for different size bolts, bolts in different positions, tightening bolts in several stages, or a cold engine vs. a warm engine.
