S-98935A034 5/8"-6 x 6 ft. ASTM A108 Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Superior wear resistance and durability with Grade 2 Carbon Steel construction and Rockwell B61 hardness, ensuring long service life in demanding industrial environments.
• Precise and predictable linear motion from the 0.167" travel distance per turn, providing accurate positioning for automation and machinery.
• Reliable thread engagement and smooth operation thanks to the Class 2G thread fit, which offers a consistent fit for nuts and reduces binding.
• High tensile strength of 64,000 psi allows the screw to withstand significant axial loads without failure.
• Broad compatibility with standard ACME nuts due to the 5/8"-6 thread size and right-hand, single-start design, simplifying system integration.
• Full-length usability with a fully threaded, 6-foot length, offering flexibility in application design and setup.
• Compliance with major environmental and material standards including RoHS 3 and REACH, ensuring safety and regulatory acceptance for global markets.

Professional Applications & Engineering Value

This 5/8"-6 ACME lead screw is engineered for precision motion control in industrial automation, CNC machinery, and lifting systems. Manufactured from Grade 2 Carbon Steel and meeting ASTM A108 specifications, it provides the necessary tensile strength and hardness to handle repetitive motion and high loads without deforming. The fully threaded and right-hand Acme thread design ensures consistent force transmission and reduces backlash, a common pain point in positioning systems. Its 0.167" travel per turn offers a balanced ratio for controlled speed and resolution, making it ideal for applications requiring accurate linear movement and durability under continuous operation.

Specification Summary & Compliance

This lead screw adheres to Class 2G thread fit tolerances for reliable assembly. It conforms to the ASTM A108 standard for material quality and is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for industrial components.
