Professional Applications & Engineering Value
This 1/4"-16 Left Hand Acme Lead Screw is engineered to solve core challenges in precision motion control systems. The Acme thread type and left-hand thread direction provide reliable, non-reversing linear motion, making it ideal for clamping devices, adjustable stages, and specialized machinery where reverse-direction force is required. Constructed from Grade 2 Carbon Steel, it delivers an optimal balance of strength (64,000 psi tensile) and machinability, resisting wear in continuous operation. The fully threaded, 3-foot length offers design flexibility, while the Class 2G thread fit minimizes play, ensuring repeatable accuracy and longevity in industrial automation, packaging, and CNC retrofit applications.
Specification Summary & Compliance
This lead screw adheres to critical dimensional and performance standards. The 1/4"-16 Acme thread is manufactured to a Class 2G thread fit, providing standard clearance for smooth operation. The material and manufacturing process comply with ASTM A108. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental regulations for hazardous substances.
