Professional Applications & Engineering Value
This left-hand Acme coupling nut solves critical reverse-thread application challenges where standard right-hand threads would compromise system functionality. Manufactured from carbon steel with controlled Rockwell B75 hardness, this component delivers optimal wear resistance in mechanical power transmission systems requiring counter-rotational movement. The 3/4"-5 Acme thread profile with Class 2G fit provides sufficient clearance for smooth operation while maintaining precise alignment in lead screw assemblies. Engineers specify this coupling nut for positioning tables, clamping devices, and lifting equipment where predictable 0.2" per turn travel enables accurate repeatability in industrial automation and motion control systems.
Specification Summary & Compliance
This Acme thread coupling nut features 3/4"-5 left-hand threads with Class 2G fit tolerance per ASME/ANSI standards. The single-start thread configuration delivers consistent 0.2" travel distance per revolution. Manufactured from carbon steel with Rockwell B75 hardness specification, this component meets general industrial requirements for mechanical power transmission applications. Dimensions include 2 1/4" height and 1" width for standardized system integration.
