Professional Applications & Engineering Value

This 3/8"-10 ACME lead screw delivers exceptional performance in fast-travel precision applications where speed and accuracy are critical. Manufactured from durable 1018 carbon steel, the component withstands continuous operation in industrial automation, CNC positioning systems, and material handling equipment. The dual thread starts and 0.2" travel distance per turn significantly reduce cycle times while maintaining ±0.009" precision over the entire 18" length. The fully threaded right-hand ACME thread design ensures consistent force distribution, eliminating common failure points in high-speed linear motion systems. This engineering solution addresses the critical need for reliable, high-velocity positioning without compromising on accuracy or durability in demanding industrial environments.

Specification Summary & Compliance

This precision lead screw features 3/8"-10 ACME threads with Class 2C thread fit tolerance, ensuring proper engagement with matching nuts. The component maintains ±0.009" per foot travel distance accuracy throughout its 18" length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, making it suitable for global industrial applications requiring strict regulatory adherence.
