Professional Applications & Engineering Value
This 3/8-8 ACME hex nut solves critical positioning challenges in linear motion systems where precision and reliability are paramount. The zinc plated carbon steel construction resists corrosion while maintaining Rockwell B75 hardness for wear resistance in high-cycle applications. The Class 2G thread fit ensures minimal backlash when paired with matching ACME lead screws, making it ideal for CNC equipment, lifting mechanisms, and automated positioning tables. With 0.125" travel per turn, engineers can achieve predictable linear displacement in packaging machinery, 3D printers, and medical device actuators without complex gearing systems.
Specification Summary & Compliance
Manufactured to ACME thread standards with Class 2G thread fit tolerance for precise engagement. The component features right-hand single-start threads measuring 3/8-8 with standard hex nut configuration for tool compatibility. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety in industrial applications. Material certification includes zinc plated carbon steel with documented Rockwell B75 hardness properties.
