Professional Applications & Engineering Value
This 3/4"-6 ACME left-hand thread lead screw is engineered for precision motion control in industrial machinery, such as CNC systems, lifting equipment, and automated positioning tables. The alloy steel construction, compliant with ASTM A193, provides exceptional strength to handle high thrust loads without deformation. The left-hand threading is critical for applications requiring counter-rotation or synchronization with right-hand components, preventing cross-threading and ensuring operational safety. With a travel distance of 0.167" per turn, it offers predictable linear advancement, reducing calibration time and improving repeatability in manufacturing processes. Its fully threaded design allows for flexible mounting and integration into complex assemblies, making it ideal for heavy-duty applications where reliability and precision are paramount.
Specification Summary & Compliance
This ACME lead screw features a 3/4"-6 thread size with Class 2G thread fit for precise engagement and smooth operation. Manufactured from ASTM Grade B7 alloy steel, it meets ASTM A193 specifications, ensuring consistent mechanical properties including a tensile strength of 125,000 psi and Rockwell C35 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible procurement and use in global markets.
