Professional Applications & Engineering Value

This 1½"-4 ACME thread brass hex nut delivers exceptional value in precision motion control systems where durability and consistent performance are critical. The 360 Brass material with Rockwell B75 hardness provides excellent corrosion resistance while maintaining the necessary strength for industrial environments. The single-start right-hand ACME threading ensures smooth, predictable linear motion with minimal vibration, making it ideal for positioning tables, lifting mechanisms, and precision manufacturing equipment. The 0.25" travel per turn offers fine control for applications requiring accurate linear displacement, while the Class 2G thread fit maintains proper clearance for reliable operation without excessive play. This nut solves common engineering challenges by combining material durability with precision threading standards for long-term reliability in mechanical power transmission systems.

Specification Summary & Compliance

This ACME lead screw nut features precision 1½"-4 thread size with Class 2G thread fit per standard inch threading tolerances. The component maintains right-hand single-start threading with 0.25" travel distance per turn for consistent linear motion performance. Manufacturing and material specifications comply with ASTM B16 standards for brass alloy composition and mechanical properties. The hex nut design measures 1½" in height and 2¼" in width for standard tool compatibility. While thrust load capacity is not rated, the Rockwell B75 hardness ensures adequate mechanical strength for typical industrial applications.
