Professional Applications & Engineering Value
This left hand Acme threaded cast iron nut delivers critical engineering solutions for industrial applications requiring reverse-direction mechanical advantage and precise linear motion control. The Rockwell B96 hardness material specification ensures exceptional durability in high-wear environments, while the Class 2G thread fit provides optimal clearance for smooth operation in Acme lead screw assemblies. The robust cast iron construction maintains dimensional stability under mechanical stress, making it ideal for positioning systems, machinery adjustment mechanisms, and applications where standard right-hand threads are impractical. The 0.125" travel per turn delivers precise movement control essential for manufacturing equipment, automated systems, and specialized industrial machinery requiring reliable left-hand thread performance.
Specification Summary & Compliance
Manufactured to inch system standards with Class 2G thread fit tolerances ensuring proper clearance for 5/8-8 left hand Acme threads. The component features a round nut configuration with 1 55/64" diameter and 1 1/4" height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting current substance restriction requirements for industrial applications worldwide.
