Professional Applications & Engineering Value

This left-hand ACME thread coupling nut is engineered to address common industrial challenges in reverse-thread applications, such as preventing unintended loosening in rotating systems or enabling precise counter-movement in machinery. Crafted from carbon steel with a Rockwell B75 hardness, it resists deformation under repetitive loads, reducing maintenance needs in demanding settings like automated actuators, clamping devices, and linear motion systems. The Class 2G thread fit and single-start Acme thread design ensure minimal friction and reliable torque transmission, while the 0.25" travel per turn supports controlled speed ratios. Ideal for mechanical coupling in industrial equipment, this nut enhances system longevity and operational safety by providing consistent, backlash-resistant performance in reverse-thread configurations.

Specification Summary & Compliance

This coupling nut adheres to inch system standards with a 1 1/2"-4 left-hand ACME thread and Class 2G thread fit for precise dimensional accuracy. Manufactured from carbon steel, it meets general industry specifications for mechanical components and is suitable for use in systems requiring reverse thread functionality. While thrust load capacity is not rated, the nut is designed for compatibility with standard ACME lead screw assemblies and aligns with common engineering practices for durability and performance.
