Professional Applications & Engineering Value
This 2 1/4"-4 ACME hex nut delivers exceptional performance in demanding linear motion systems and precision machinery. Crafted from 18-8 stainless steel, it resists corrosion in humid or chemical-exposed settings, extending service life. The Class 2G thread fit minimizes play, crucial for applications requiring exact positioning like CNC equipment, lifting mechanisms, and valve actuators. With a 0.25" travel per turn, it provides predictable movement in lead screw assemblies, reducing calibration time. The right-hand thread direction ensures compatibility with standard components, while the hex nut configuration allows for secure tightening in confined spaces, making it a reliable choice for industrial maintenance and OEM designs.
Specification Summary & Compliance
This ACME hex nut features a 2 1/4"-4 thread size with Class 2G thread fit per standard inch measurements, ensuring dimensional accuracy and interchangeability. It complies with RoHS 3 (2015/863/EU) regulations, supporting environmental safety in manufacturing. The 18-8 stainless steel material and Rockwell B97 hardness confirm consistent mechanical properties, suitable for general industrial use where high loads are not rated.
