Professional Applications & Engineering Value
This 3/4"-5 ACME lead screw delivers exceptional performance in precision motion control systems where reliability and accuracy are critical. Manufactured from zinc plated carbon steel, it resists corrosion while maintaining Rockwell B61 hardness for long service life in CNC machinery, linear actuators, and industrial automation equipment. The fully threaded design with right-hand threading enables consistent force transmission across the entire 6-foot length, while the Class 2G thread fit minimizes play and vibration in high-cycle applications. Engineers specify this component for its predictable 0.2" travel per turn, which ensures repeatable positioning in material handling, packaging, and manufacturing systems where dimensional stability is paramount.
Specification Summary & Compliance
This ACME lead screw features 3/4"-5 thread size with Class 2G thread fit per inch system standards. Manufactured to ASTM A108 specifications with Grade 2 carbon steel construction, it delivers 68,000 psi tensile strength and Rockwell B61 hardness. The component is RoHS 3 (2015/863/EU) Compliant and features right-hand threading with fully threaded configuration across its 6-foot length, ensuring consistent performance in industrial motion control applications.
