Professional Applications & Engineering Value

This 1/2"-10 Left Hand Acme Lead Screw delivers exceptional value in precision motion control applications where reverse-direction operation is required. Engineered from Grade 2 Carbon Steel with Rockwell B61 hardness, it provides superior resistance to wear and deformation in demanding industrial environments. The fully threaded ACME design with 0.1" travel per turn ensures precise linear movement in CNC machinery, lifting equipment, and automated positioning systems. The left-hand threading is particularly valuable in applications requiring counter-rotational movement or where standard right-hand threads would create operational conflicts. This industrial lead screw solves critical engineering challenges by offering predictable performance, minimal backlash, and long-term reliability in continuous operation scenarios.

Specification Summary & Compliance

This Acme lead screw features 1/2"-10 thread size with Class 2G thread fit tolerance for optimal performance in inch-system applications.
