Professional Applications & Engineering Value

This left-hand Acme threaded nut is engineered to solve critical challenges in precision motion control systems where standard right-hand threads are unsuitable. The cast iron body, with its inherent strength and Brinell 217 hardness, resists deformation under heavy loads, making it ideal for industrial machinery, CNC equipment, and lifting mechanisms. The Acme thread form provides high efficiency and load-bearing capacity, while the Class 2C thread fit minimizes play for accurate positioning. Its 0.25" travel per turn allows for fine adjustments, crucial in applications requiring precise linear displacement. This component is a reliable choice for engineers seeking durable, compliant parts for demanding environments.

Specification Summary & Compliance

This nut adheres to inch system measurements with a thread size of 1 1/4"-4 and a Class 2C thread fit per standard Acme threading specifications, ensuring dimensional accuracy and interchangeability. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances. The component meets industry standards for Acme thread applications, providing reliable performance in mechanical assemblies requiring left-hand threading for specialized motion control.
