Professional Applications & Engineering Value

This left hand ACME hex nut delivers critical engineering solutions for industrial applications requiring reverse-direction linear motion. The combination of zinc plated carbon steel construction and Rockwell B75 hardness provides exceptional resistance to mechanical wear and environmental corrosion, making it ideal for manufacturing equipment, automated systems, and machinery where ACME thread specifications demand reliable performance. The Class 2G thread fit ensures consistent engagement with mating components while the left-hand thread direction prevents unintended loosening in rotating systems. With 0.2" travel per turn, this nut offers precise motion control for positioning tables, clamping devices, and other precision mechanical assemblies where backlash minimization and repeatable movement are essential.

Specification Summary & Compliance

This 1"-5 left hand ACME hex nut features Class 2G thread fit per standard ACME thread specifications, ensuring proper clearance for smooth operation. Manufactured from carbon steel with zinc plating for corrosion protection and hardened to Rockwell B75 for mechanical durability. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental standards for industrial use. Designed with single thread start configuration and standard hex nut profile for compatibility with conventional installation tools and procedures.
