S-99030A434 3/8"-16 x 6 ft. Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Exceptional positioning accuracy with ±0.009" per foot tolerance for reliable, repeatable motion control in automated systems.
• Superior load-bearing capability from 1018 Carbon Steel construction, offering a high tensile strength of 64,000 psi for demanding industrial applications.
• Optimized for reverse-threading applications with a left-hand Acme thread, providing unique mechanical solutions where standard right-hand threads are unsuitable.
• Consistent, predictable linear motion with a 0.063" travel distance per turn and a 1:1 speed ratio for straightforward velocity and position calculations.
• Enhanced durability and wear resistance due to a Brinell hardness of 126, ensuring a long service life even under continuous operation.
• Broad compatibility and easy integration with a Class 2C thread fit, designed for applications where quick assembly and disassembly are required.
• Guaranteed environmental and safety compliance by meeting RoHS 3 and REACH standards, making it suitable for global supply chains and regulated industries.

Professional Applications & Engineering Value

This 3/8-16 Left Hand Acme Lead Screw is engineered to solve critical challenges in motion control systems requiring reverse-direction operation or specific mechanical advantages. The 1018 Carbon Steel construction provides the necessary tensile strength and rigidity for applications like clamping mechanisms, lifting equipment, and precision positioning tables where load capacity and durability are paramount. The left-hand Acme threading is particularly valuable in assemblies involving multiple lead screws to prevent loosening under counter-rotational forces or to create specific mechanical movements in conveyor systems and machine tools. With its fully threaded 6-foot length and single-start thread design, it delivers consistent, backlash-resistant linear motion, making it an ideal component for OEMs and maintenance teams in packaging, automotive, and industrial automation sectors seeking reliable, long-lasting precision Acme screw solutions.

Specification Summary & Compliance

This Acme lead screw adheres to Class 2C thread fit standards, providing the necessary clearance for efficient operation in non-critical, freely-assembling applications. Manufactured to precise dimensional tolerances in the inch system, it ensures compatibility with a wide range of nut components and mounting hardware. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and internationally regulated markets without hazardous substance restrictions.
