Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with 125,000 psi tensile strength, ideal for high-stress industrial applications.
- Superior wear resistance and durability due to Rockwell C35 hardness and ASTM Grade B7 alloy steel construction.
- Precise and reliable motion control with 0.083" travel per turn and Class 2G thread fit for smooth, backlash-free operation.
- Left-hand threading design enables unique mechanical setups and prevents unintended loosening in specific directional movements.
- Full-length threading ensures consistent engagement and flexibility in positioning across the entire 6 ft. length.
- Compliance with rigorous standards including ASTM A193, RoHS 3, and REACH, guaranteeing safety and environmental responsibility.
- Single-start Acme thread provides efficient power transmission and ease of assembly in repetitive motion systems.
Professional Applications & Engineering Value
This 3/8"-12 Left Hand Acme Lead Screw is engineered to address critical challenges in precision motion control systems, such as CNC machinery, linear actuators, and heavy-duty clamping devices. The ASTM Grade B7 alloy steel composition, combined with Acme threading and Class 2G thread fit, ensures minimal friction and high torque efficiency, reducing wear and maintenance downtime. Its left-hand thread direction is particularly valuable in counter-rotational assemblies, preventing accidental disengagement. With a tensile strength of 125,000 psi and full threading, it supports consistent, high-load operations in industrial environments, enhancing system reliability and longevity.
Specification Summary & Compliance
This lead screw adheres to Class 2G thread fit tolerances for precise engagement and features a 3/8"-12 Acme thread with single-start design. It complies with ASTM A193 manufacturing standards and is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence.
