Professional Applications & Engineering Value
This 1/4-16 ACME lead screw is engineered to address critical challenges in precision motion control systems, such as CNC machinery, automated actuators, and linear positioning equipment. The fully threaded design and right-hand ACME threading provide consistent force transmission and minimal friction, reducing energy loss and maintenance downtime. Constructed from ASTM Grade B7 alloy steel, it maintains dimensional stability under heavy loads and thermal cycling, preventing deformation in high-temperature environments. The Class 2G thread fit ensures precise alignment with mating components, enhancing operational accuracy in repetitive industrial tasks. By combining high tensile strength with Rockwell C35 hardness, this lead screw delivers long-term reliability in applications requiring durable, low-backlash motion solutions.
Specification Summary & Compliance
This lead screw adheres to Class 2G thread fit tolerances for precise ACME thread engagement, manufactured in compliance with ASTM A193 specifications. It features a 1/4"-16 ACME thread with right-hand direction and fully threaded 12-inch length, ensuring consistent performance in motion control assemblies. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, confirming its suitability for regulated industrial markets.
