Considering that You can utilize extra torque, it signifies that it can be tightened much more than other screws, so is considered a safer screw,

The strain-velocity, or PV aspect, is the products on the stress and velocity concerning the nut and screw. It can help figure out the load, speed and responsibility cycle the nut can handle. Plastic products have an intrinsic PV score, The purpose at which frictional heat causes lasting deformation from the plastic. So the more load placed on a lead screw assembly, the slower it should be turned to stop exceeding the nut’s PV limit.
