• Optimized for reverse or counter-rotation mechanisms with a left-hand Acme thread, providing design flexibility in motion systems.
• Reliable, free-running assembly with a Class 2C thread fit, reducing binding and ensuring smooth operation with matching nuts.
• Consistent and predictable linear movement with a 0.167" travel distance per turn from a single-start thread design.
• Compliant with global environmental standards (RoHS 3), making it suitable for use in regulated markets and eco-conscious projects.

Professional Applications & Engineering Value

This precision Acme lead screw is engineered to solve critical challenges in industrial motion control. The 304 Stainless Steel material provides excellent corrosion resistance, making it suitable for food processing, medical equipment, and other applications requiring frequent cleaning or exposure to corrosive agents. The left-hand thread direction is essential for specialized machinery where reverse-thread operation is needed to prevent loosening under specific torque conditions or to synchronize with other components. Its high tensile strength and defined travel accuracy ensure that systems maintain precise linear positioning over time, reducing downtime and maintenance costs. This makes it an invaluable component in CNC machinery, precision actuators, and automated positioning systems where reliability and accuracy are non-negotiable.

Specification Summary & Compliance

This 3/4"-6 Acme lead screw adheres to standard inch system measurements with a Class 2C thread fit for a free-running assembly. It is fully threaded with a single-start Acme thread and a consistent travel distance of 0.167" per turn. The component is manufactured to ensure dimensional accuracy and is RoHS 3 (2015/863/EU) compliant, meeting stringent environmental directives for hazardous substance restrictions.
