Professional Applications & Engineering Value

This 1/4"-16 left hand Acme lead screw delivers critical engineering value in applications requiring precise linear motion with reverse-direction capability. The 1018 carbon steel construction provides the optimal balance of strength and machinability, while the Class 2C thread fit ensures reliable performance in industrial environments where clearance and smooth operation are paramount. The left-hand Acme threading solves specific engineering challenges in applications such as clamping systems, adjustable mechanisms, and specialized machinery where standard right-hand threads cannot provide the required directional movement. With ±0.009" per foot accuracy, this fully threaded component maintains precise positioning over its entire 3-foot length, making it ideal for CNC systems, automated equipment, and precision manufacturing applications where consistent travel distance per turn is critical for repeatable results.
