Professional Applications & Engineering Value
This 3/8-8 ACME lead screw delivers critical performance advantages in precision motion systems where reliability and accuracy are paramount. The zinc plated carbon steel construction provides essential corrosion protection for industrial environments while maintaining the Grade 2 strength rating required for continuous operation. The fully threaded design with single start Acme threading ensures consistent power transmission across the entire 12" length, making it ideal for CNC equipment, linear actuators, and positioning systems. With its 0.125" travel per turn, engineers achieve precise linear movement control without the slippage concerns of alternative thread forms, while the right-hand thread direction maintains compatibility with standard industrial components.
Specification Summary & Compliance
This ACME lead screw features precise 3/8-8 thread size with Class 2G thread fit tolerances for optimal performance in power transmission applications. Manufactured to ASTM A108 specifications from Grade 2 carbon steel with Rockwell B61 hardness, it delivers 68,000 PSI tensile strength. The component is RoHS 3 (2015/863/EU) compliant and features fully threaded construction with single start, right-hand Acme threads for consistent operation across industrial automation and motion control systems.
