Professional Applications & Engineering Value
This 2"-4 ACME left-hand thread lead screw delivers exceptional performance in precision motion control systems where reliability and accuracy are paramount. The ASTM Grade B7 alloy steel construction provides outstanding strength-to-weight ratio, resisting deformation under heavy loads while the ACME thread profile ensures efficient power transmission with minimal backlash. The left-hand threading is particularly valuable in applications requiring counter-rotational movement or where standard right-hand threads would create operational conflicts. With its 0.25" travel per turn and Class 2G thread fit, this fully threaded lead screw maintains precise positioning in industrial automation, CNC machinery, lifting equipment, and precision manufacturing systems where consistent performance under continuous operation is essential.
Specification Summary & Compliance
This ACME lead screw features a 2"-4 left-hand thread with Class 2G thread fit tolerance, ensuring precise engagement and smooth operation. Manufactured from ASTM Grade B7 alloy steel meeting ASTM A193 specifications, it delivers 125,000 psi tensile strength and Rockwell C35 hardness. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring both high performance and environmental responsibility.
