Professional Applications & Engineering Value

This ACME left-hand thread lead screw solves critical positioning challenges in industrial automation and heavy machinery. The ASTM Grade B7 alloy steel construction provides exceptional resistance to deformation under continuous loads, while the Class 2G thread fit maintains precise engagement throughout the fully threaded 3-foot length. The left-hand threading enables unique mechanical configurations where standard right-hand threads would be impractical, particularly in synchronized multi-axis systems. With 0.1" travel per turn, engineers achieve predictable linear motion in pressing equipment, valve actuators, and precision lifting mechanisms where controlled movement and positioning accuracy are paramount. The combination of 125,000 psi tensile strength and Rockwell C35 hardness ensures reliable performance in high-cycle applications without premature wear or failure.

Specification Summary & Compliance

Manufactured to Class 2G thread fit tolerances with 1/2"-10 ACME left-hand threading and single thread start configuration. Complies with ASTM A193 material specifications for Grade B7 alloy steel components. Meets RoHS 3 (2015/863/EU) compliance standards and REACH (EC 1907/2006) requirements for hazardous substance restrictions. The fully threaded design maintains consistent 0.1" travel distance per turn across the entire 3-foot length, ensuring uniform performance in linear motion applications.
