Professional Applications & Engineering Value
This left-hand ACME thread nut in 360 Brass is engineered to address critical challenges in precision motion systems, such as backlash reduction and corrosion prevention. The Class 2G fit and Acme thread type provide smooth, low-friction engagement with lead screws, minimizing wear in repetitive operations common in automation, CNC machinery, and lifting equipment. Its left-hand thread direction is particularly valuable for applications requiring counter-rotational stability or dual-motion setups. With a Rockwell B55 hardness, it maintains dimensional integrity under mechanical stress, while the ASTM B16 certification ensures consistent material properties, reducing downtime and maintenance costs in industrial environments.
Specification Summary & Compliance
This nut features a 7/8"-6 left-hand ACME thread with Class 2G fit per standard inch system tolerances, ensuring precise thread engagement. It complies with ASTM B16 specifications for brass materials, confirming quality in composition and manufacturing. The product adheres to industry standards for dimensional accuracy, including a defined travel distance of 0.167" per turn and a 1:1 speed ratio, supporting reliable performance in mechanical assemblies without specific thrust load ratings.
