Professional Applications & Engineering Value
This 3/8"-16 ACME lead screw is engineered to solve core challenges in precision motion control. The 1018 carbon steel material offers a robust balance of machinability and strength, resisting deformation under load in applications like CNC positioning, automated assembly lines, and precision lifting equipment. The ACME thread type and Class 2C thread fit are specifically chosen to provide a combination of high efficiency and durability, with built-in clearance to accommodate misalignment and reduce wear. This makes it an ideal linear motion component for systems requiring reliable, long-term operation without frequent maintenance, effectively minimizing downtime and operational costs in industrial settings.
Specification Summary & Compliance
This lead screw features a 3/8"-16 thread size with ACME thread form and Class 2C thread fit per inch system standards, ensuring dimensional accuracy and interchangeability. It is manufactured as a fully threaded component with a single start, right-hand direction, and a consistent travel distance of 0.063" per turn. The product is confirmed to be compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its adherence to strict environmental and safety standards for global engineering use.
