Product Overview

This ACME, precision lead screw with two (2) starts has right hand threads of five (5) turns per inch. The lead screw is made from high strength 4140 steel. The 6 in. option has a machined end, details can be found on the print at the bottom of the page. 

The bronze nut rides smoothly over the lead screw threads, and has it's own threads on the outside diameter in order to be mounted into a tube, shaft, or housing. This pair is useful in many robotic applications to turn rotational motion from a motor into linear motion as the nut travels the length of the lead screw. This is the lead screw and nut that was used on the DART linear actuator.

These PowerAC™ Inch Acme screws and nuts include a centralizing thread form to prevent wedging and binding. When compared to general-purpose thread forms, centralizing threads are manufactured with tighter tolerances and reduced clearance on the major diameter to increase precision and reduce issues.
