The pressure-velocity, or PV variable, will be the product with the stress and velocity between the nut and screw. It helps ascertain the load, speed and responsibility cycle that the nut can tackle. Plastic components have an intrinsic PV score, The Full Report purpose at which frictional heat results in everlasting deformation of the plastic. So the greater load applied to a lead screw assembly, the slower it has to be turned in order to avoid exceeding the nut’s PV Restrict.
A probable adaptation to your Phillips head, the tri-wing screw has a small triangular center with a few wings extending through the details.
