Professional Applications & Engineering Value

This left hand Acme plastic nut delivers exceptional value in applications requiring precise reverse linear motion, such as clamping systems, positioning stages, and automated equipment where standard right-hand threads are insufficient. The PET plastic material offers inherent corrosion resistance and low friction operation, eliminating the need for lubrication in sensitive environments. With its 0.167" travel per turn and 1450 lbs dynamic thrust load capacity, this component provides reliable performance in packaging machinery, medical devices, and food processing equipment where contamination from metal components or lubricants must be avoided. The left-hand thread direction enables unique mechanical arrangements for tensioning, counter-rotation, and safety mechanisms in industrial automation systems.

Specification Summary & Compliance

This inch-system 3/4"-6 Acme plastic nut features Class 2C thread fit for optimal clearance in general purpose applications. Manufactured from PET plastic with a round nut configuration, the component delivers precise 0.167" travel distance per turn with single thread start design. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance across global markets. Operating temperature range spans from 15° to 175° F, making it suitable for most industrial environments.
