Professional Applications & Engineering Value
This 3/8-12 ACME lead screw solves critical motion control challenges in industrial automation, CNC machinery, and precision positioning systems. The ASTM Grade B7 alloy steel construction withstands high tensile loads while maintaining dimensional stability, preventing deformation under continuous operation. The ACME thread form with Class 2G fit ensures reliable engagement with mating nuts, reducing backlash and improving positional accuracy. With 0.083" travel per turn, engineers achieve precise linear motion control in applications requiring repeatable movement, from manufacturing equipment to material handling systems. The fully threaded design allows for flexible mounting configurations while the right-hand thread direction provides standard motion transfer compatible with most industrial drives.
Specification Summary & Compliance
Manufactured to ASTM A193 standards with Class 2G thread fit tolerances ensuring proper clearances for ACME thread applications. The inch-system component features 3/8"-12 ACME threads with single-start configuration and right-hand direction. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for international industrial markets requiring verified material safety standards.
