Professional Applications & Engineering Value

This left-hand Acme thread nut manufactured from 932 Bearing Bronze addresses critical engineering challenges in industrial motion systems. The bronze composition provides natural lubricity that reduces galling and wear in high-load, low-speed applications where continuous lubrication isn't feasible. The Class 2G thread fit offers optimal clearance for smooth operation while maintaining precision in Acme lead screw assemblies. This combination proves invaluable in reversing mechanisms, clamping systems, and precision positioning equipment where left-hand threading prevents unintended loosening under counter-clockwise rotation. The material's corrosion resistance and ASTM B505 compliance ensure reliable performance in manufacturing, automation, and heavy machinery applications where component failure would cause significant downtime.

Specification Summary & Compliance

This Acme thread nut features 1/2"-10 left-hand threading with Class 2G fit per standard Acme thread specifications, providing appropriate clearance for smooth operation. Manufactured from 932 Bearing Bronze conforming to ASTM B505 material standards. The component is RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloys. With 0.1" travel per turn and compact 29/32" diameter and height dimensions, this round nut delivers precise motion control in industrial applications requiring reliable threaded components.
