Professional Applications & Engineering Value

This 5/8"-5 Left Hand Acme Lead Screw is engineered for precision motion control in industrial automation, CNC machinery, and heavy-duty positioning systems. The hardened 4140 alloy steel construction and Class 2C thread fit deliver exceptional strength and minimal backlash, solving common issues like positional drift and component wear. Its black-oxide surface treatment enhances corrosion resistance, making it ideal for environments exposed to moisture or chemicals. With a consistent 0.2" travel per turn and high tensile strength, it ensures reliable performance in applications requiring reverse-direction actuation, such as clamping mechanisms and linear drives, reducing downtime and maintenance costs.

Specification Summary & Compliance

This lead screw adheres to inch system measurements with a Class 2C thread fit for standard industrial compatibility. It features a fully threaded, single-start Acme thread with left-hand direction, manufactured to precise travel distance accuracy of ±0.009" per foot. The component complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from restricted hazardous substances, and meets general industry standards for material properties and dimensional tolerances.
