Professional Applications & Engineering Value
This precision ACME lead screw is engineered to solve critical challenges in industrial automation and motion control systems. The hardened 4140 alloy steel construction, combined with a black-oxide surface treatment, resists corrosion and abrasion in demanding settings like CNC machinery, linear actuators, and packaging equipment. Its Class 2C thread fit and fully threaded, right-hand design ensure smooth, backlash-free operation, while the ±0.009" per ft accuracy minimizes positional errors in high-precision applications. By delivering consistent travel distance per turn (0.1") and high tensile strength, it reduces maintenance downtime and enhances the reliability of mechanical drives.
Specification Summary & Compliance
This 3/8"-10 ACME lead screw adheres to inch system standards with a Class 2C thread fit for precise nut engagement. It features a single-start, right-hand thread and is fully threaded along its 3 ft length. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety. The hardened 4140 alloy steel maintains Brinell 271 hardness and 125,000 psi tensile strength, supporting use in rigorous industrial applications.
