Professional Applications & Engineering Value

This 5/8"-8 Left Hand Acme Lead Screw delivers critical engineering solutions for industrial applications requiring reverse-direction linear motion. The Grade 2 Carbon Steel construction provides the optimal balance of strength and machinability, while the Rockwell B61 hardness ensures excellent wear resistance in continuous operation. The left-hand ACME threading is specifically engineered for applications where conventional right-hand threads would back out under load, making it ideal for clamping systems, precision positioning equipment, and specialized machinery. With 0.125" travel per turn and Class 2G thread fit, this fully threaded lead screw offers predictable movement and reduced play, essential for repeatable processes in manufacturing, automation, and material handling systems where precision linear motion is paramount.

Specification Summary & Compliance
