ABSTRACT:
The threads of a nut on a multithreaded, high helix lead screw are formed by disposing a nut over a lead screw where the center hole of the nut is larger than the threads of the lead screw. Polymer material is filled into the space between the nut and the lead screw and cured to form a high helix, multithreaded nut which has threads complimentary to the threads of the lead screw.
