Professional Applications & Engineering Value
This 3/8-12 ACME lead screw in ASTM Grade B7 alloy steel is engineered to address common industrial challenges such as high-load fatigue and precision loss in linear motion systems. The Acme thread type and fully threaded construction provide excellent power transmission and uniform stress distribution, minimizing the risk of thread stripping under heavy cyclic loads. With a tensile strength of 125,000 psi and Rockwell C35 hardness, it excels in applications like CNC machinery, material handling equipment, and automotive actuators, where consistent performance and long service life are critical. The right-hand thread direction and standardized dimensions ensure easy replacement and interoperability in existing setups, reducing downtime and maintenance costs for B2B clients.
Specification Summary & Compliance
This lead screw adheres to Class 2G thread fit tolerances for precise assembly, with threading conforming to Acme standards for reliable engagement. It meets ASTM A193 specifications for material and manufacturing quality, and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
