• Enhanced durability with Brinell 126 hardness rating, resisting wear and deformation in continuous operation environments.
• Broad compatibility with Class 2C thread fit standards, ensuring proper engagement with matching nuts while accommodating minor misalignments.
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for use in environmentally conscious manufacturing facilities.

Professional Applications & Engineering Value

This ACME left-hand thread lead screw solves critical positioning challenges in industrial automation, CNC machinery, and precision lifting systems. The 1018 carbon steel construction provides the ideal balance of strength and machinability, while the fully threaded design ensures consistent force distribution along the entire 6-foot length. Engineers specify this component for applications requiring reverse motion capabilities or where multiple screw assemblies must operate in opposition. The Class 2C thread fit accommodates thermal expansion and minor installation variances without compromising performance. With its single-start thread and precise 0.2" travel per turn, this lead screw delivers predictable linear motion for packaging equipment, 3D printers, and material handling systems where accuracy and reliability are paramount.

Specification Summary & Compliance

This precision ACME lead screw maintains dimensional accuracy per Class 2C thread fit standards with 1-1/4"-5 thread size and left-hand thread direction. Manufacturing adheres to industry-standard tolerances for travel distance per turn (±0.009" per ft.) and thread form. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while meeting global manufacturing requirements for hazardous substance restrictions.
