The tension-velocity, or PV issue, may be the item in the pressure and velocity concerning the nut and screw. It helps identify the load, velocity and responsibility cycle that the nut can manage. Plastic components have an intrinsic PV score, The purpose at which frictional warmth will cause lasting deformation on the plastic. So the greater load applied to a lead screw assembly, the slower it should be turned to stop exceeding the nut’s PV limit.
A countersunk screw head is where the head is sunk into your workpiece or challenge. This means the head gets flush into the surface and is not uncovered.
