Professional Applications & Engineering Value

This 316 Stainless Steel ACME Lead Screw is engineered to solve critical challenges in precision motion control and positioning systems. The ACME thread profile provides high efficiency and load-bearing capacity, making it superior to standard V-threads for applications requiring precise linear movement with minimal backlash. The Class 2G thread fit offers an optimal balance between ease of assembly and operational precision, reducing wear in high-cycle applications. Its corrosion-resistant properties are essential for food processing, medical, marine, and chemical handling equipment where moisture and corrosive agents are present. The single-start thread and consistent 0.063" travel per turn deliver repeatable accuracy in CNC machines, 3D printers, valve actuators, and lifting mechanisms, ensuring reliable performance where dimensional stability and material integrity are non-negotiable.

Specification Summary & Compliance

This 1/4-16 ACME threaded lead screw features a Class 2G thread fit per inch-system standards, ensuring dimensional accuracy and interchangeability. It is manufactured from ASTM A193 Grade B8M 316 stainless steel, providing a tensile strength of 75,000 psi and a hardness of Rockwell B97. The component is fully threaded with a right-hand thread direction and is compliant with RoHS 3 (2015/863/EU) regulations, making it suitable for use in products sold in the EU and other regulated markets.
