Professional Applications & Engineering Value

This left-hand Acme lead screw solves critical positioning challenges in industrial automation where reverse-direction linear motion is required. The 1018 Carbon Steel construction provides optimal strength-to-weight ratio for applications like packaging machinery, CNC retrofits, and material handling systems. With Class 2C thread fit and ±0.009" per foot accuracy, it eliminates positional drift in precision indexing applications while the fully threaded design allows for unlimited carriage positioning along the entire 3-foot length. The left-hand Acme threading enables creation of opposing motion systems using standard right-hand components, reducing engineering complexity and inventory requirements for maintenance teams.

Specification Summary & Compliance

This 1"-10 Acme lead screw maintains Class 2C thread fit tolerances per ASME B1.5 standards, ensuring consistent performance across industrial applications. The component features single-start threading with 0.1" travel distance per revolution and left-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, making it suitable for use in regulated industries worldwide. Mechanical properties include 64,000 psi tensile strength and Brinell 126 hardness rating for dependable operation in demanding motion control systems.
