Thread: The thread could be the structure to blame for converting rotational motion into linear motion given that the screw shaft and also the nut slide with one another.
Finer threads are much better as they have a larger tension location for the same diameter thread. Fantastic threads are more unlikely to vibrate free as they've got a scaled-down helix angle and permit finer adjustment. Finer threads produce larger preload with a lot less tightening torque.[five]
