- Precise linear motion control with consistent 0.125" travel distance per turn for accurate positioning
- Optimized thread engagement through Class 2G fit provides smooth operation with minimal backlash
- Enhanced mechanical strength from Rockwell B97 hardness maintains thread integrity under repeated use
- Secure hex installation allows for standard wrench access and reliable torque application
- Environmental compliance with RoHS 3 standards ensures safe use across regulated industries
Professional Applications & Engineering Value
This left-hand Acme hex nut delivers critical engineering value in applications requiring reverse-thread security and precise linear motion. The 3/8-8 Acme thread configuration with Class 2G fit provides exceptional anti-backlash performance in automated systems, while the 18-8 stainless steel construction offers superior corrosion resistance for harsh manufacturing environments. The combination of Rockwell B97 hardness and precise 0.125" travel per turn makes this component ideal for positioning systems, clamping devices, and motion control applications where reverse threading prevents accidental disengagement. Its left-hand thread direction specifically addresses safety-critical applications in machinery where standard right-hand threads would pose operational risks.
Specification Summary & Compliance
Manufactured to inch system standards with 3/8-8 left-hand Acme threads and Class 2G thread fit for precise engagement. The component features a hex nut configuration with dimensions of 23/64" height and 11/16" width. Material specifications include 18-8 stainless steel with Rockwell B97 hardness rating. Compliance includes RoHS 3 (2015/863/EU) environmental standards, ensuring restriction of hazardous substances for industrial safety.
