Key Features & Benefits at a Glance
- Precise Motion Control: Achieve accurate linear movement with consistent 0.25" travel per turn, ideal for repetitive positioning tasks.
- Exceptional Load Capacity: Withstand heavy-duty applications thanks to the high 125,000 psi tensile strength of the ASTM Grade B7 alloy steel.
- Superior Wear Resistance: Rockwell C35 hardness ensures long-term durability and reduced wear in high-friction environments.
- Reliable Thread Engagement: Class 2G thread fit provides optimal clearance for smooth operation and minimal backlash in assembly.
- Left-Hand Thread Versatility: Enables unique mechanical setups and reverse motion applications where standard right-hand threads are unsuitable.
- Full Threading for Maximum Utility: Entire 6 ft. length is threaded, offering flexibility in mounting and engagement points.
- Compliant for Global Use: Meets RoHS 3 and REACH environmental standards, ensuring safe integration into international projects.
Professional Applications & Engineering Value
This 2"-4 ACME left-hand thread lead screw is engineered to solve critical challenges in industrial motion control systems. The ASTM Grade B7 alloy steel construction, combined with ACME threading, provides high torque capacity and efficient power transmission, reducing the risk of stripping under heavy loads. The single-start thread and 0.25" travel per turn deliver precise linear actuation, making it ideal for CNC machinery, lifting equipment, and valve actuators where accuracy and reliability are paramount. Its fully threaded design and left-hand direction offer installation flexibility for specialized configurations, while the robust material properties minimize elongation and maintain dimensional stability in continuous operation.
Specification Summary & Compliance
This lead screw features a 2"-4 ACME thread with Class 2G thread fit per standard inch system tolerances, ensuring compatibility with corresponding nuts. It is manufactured in compliance with ASTM A193 Grade B7 specifications, providing verified mechanical properties including tensile strength and hardness. The component adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated industries without hazardous substance restrictions.
