Professional Applications & Engineering Value
This 1"-8 left-hand Acme lead screw delivers exceptional performance in precision motion control systems where reliability and accuracy are paramount. Engineered from Grade 2 carbon steel and heat-treated to Rockwell B61 hardness, it provides superior resistance to wear and deformation under continuous operation. The fully threaded design with single-start Acme threading ensures consistent force transmission and positioning accuracy across the entire 6-foot length. The left-hand thread direction offers unique solutions for applications requiring reverse motion or specialized mechanical arrangements that standard right-hand threads cannot accommodate. With 0.125" travel per turn, this lead screw provides precise linear motion control for industrial automation, CNC machinery, lifting equipment, and positioning systems where backlash must be minimized and repeatability is critical.
Specification Summary & Compliance
This Acme lead screw features 1"-8 left-hand threading with Class 2G thread fit tolerance for optimal performance in inch-system applications. Manufactured from Grade 2 carbon steel with 64,000 psi tensile strength and Rockwell B61 hardness, it meets ASTM A108 specifications for material quality and performance. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and environmentally conscious manufacturing operations.
