- Superior durability and wear resistance thanks to hardened Black-Oxide 4140 alloy steel construction with Brinell 271 hardness.
- High load-bearing capacity supported by 125,000 psi tensile strength, ideal for demanding industrial applications.
- Consistent thread engagement and reduced backlash with Class 2C thread fit, maintaining accuracy over extended use.
- Corrosion-resistant surface protection from the black-oxide finish, extending service life in harsh environments.
- Full-threaded, right-hand design for seamless integration and reliable performance in motion control assemblies.
Professional Applications & Engineering Value
This 3/8"-10 ACME lead screw is engineered to address critical challenges in precision motion systems, such as positioning accuracy and high-speed operation. The Black-Oxide 4140 alloy steel material, combined with hardening, provides exceptional strength and resistance to wear, reducing maintenance needs in CNC machinery, linear actuators, and automated packaging equipment. With a 0.2" travel per turn and dual thread starts for a 2:1 speed ratio, it enables faster cycle times without sacrificing precision, making it ideal for applications requiring rapid, repeatable movements. The fully threaded and right-hand Acme threading ensures smooth force transmission and compatibility with standard nuts, enhancing reliability in industrial settings where downtime is costly.
Specification Summary & Compliance
This lead screw adheres to Class 2C thread fit standards for consistent thread engagement and minimal backlash. It is manufactured from hardened 4140 alloy steel with a black-oxide surface treatment, providing corrosion resistance and durability. The product meets RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances, and is suitable for use in regulated industries requiring environmental and safety standards.
