Professional Applications & Engineering Value

This precision Acme nut delivers exceptional value in linear motion systems requiring reverse-direction operation. The left-hand Acme threading (1"-5) with Class 2G fit provides reliable engagement in applications where standard right-hand threads would loosen under specific motion patterns. Manufactured from 360 Brass with Rockwell B55 hardness, this component offers superior wear characteristics compared to standard fasteners, significantly reducing maintenance intervals in high-cycle equipment. The square nut design enhances installation stability while the 0.2" travel per turn delivers precise positional control in automated machinery, valve actuators, and precision positioning systems. Meeting ASTM B16 specifications, this nut ensures consistent performance in industrial automation, packaging equipment, and motion control assemblies where reliability and repeatability are critical.

Specification Summary & Compliance

This Acme threaded nut features 1"-5 left-hand threading with Class 2G thread fit per ANSI/ASME B1.5 standards, ensuring proper clearance for smooth operation. The component maintains dimensional accuracy with 0.2" travel distance per turn and single thread start configuration. Manufactured from 360 Brass in compliance with ASTM B16 specifications for brass rod, bar, and shapes. The square nut measures 1" height × 1-5/8" width with Rockwell B55 hardness rating. While thrust load capacity is not rated, the component is designed for general industrial applications requiring precision linear motion with left-hand thread direction.
