The lead angle is definitely the complementary angle of the helix angle. It is the angle amongst the helical thread and also the axis of rotation.
The angle fashioned in between the helical thread Along with the perpendicular axis of your lead screw shaft is referred to as the helix angle. A bigger helix angle involves extra torque to move the nut nevertheless it brings about reduce friction losses, So earning the set up much more effective.
Self-tapping screws can be utilized to hitch two parts of material jointly. They are really intended having a pointed tip and sharp threads that enable them to tap into the material as They can be pushed in, which results in their particular mating thread.
