Professional Applications & Engineering Value
This 5/8-8 ACME left-hand thread lead screw solves critical engineering challenges in precision motion control systems where reverse-direction operation is required. The 1018 carbon steel construction provides the ideal balance of strength and machinability, while the Class 2C thread fit ensures smooth engagement with mating nuts, reducing wear and maintenance requirements. The ±0.009" per foot travel accuracy makes this component particularly valuable in applications requiring precise linear positioning, such as CNC machinery, automated assembly systems, and precision measurement equipment. The left-hand ACME threading enables unique mechanical configurations in packaging machinery, medical devices, and specialized industrial automation where conventional right-hand threads would be insufficient.
Specification Summary & Compliance
This precision ACME lead screw features 5/8-8 thread size with Class 2C fit tolerances, single start configuration, and 0.125" travel distance per turn. Manufactured from 1018 carbon steel with Brinell 126 hardness, the component delivers 64,000 psi tensile strength. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for use in regulated industries and international markets.
