S-99030A505 1/2"-10 x 6 ft. Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Exceptional travel accuracy of ±0.009" per foot ensures reliable positioning and repeatable motion control in automated systems.
• Durable 1018 Carbon Steel construction provides high tensile strength (64,000 psi) and hardness (Brinell 126) for long service life under heavy loads.
• Left-hand Acme threading offers specialized motion solutions for applications requiring reverse-direction drive or counter-clockwise advancement.
• Class 2C thread fit delivers optimal clearance for smooth operation with minimal backlash when paired with matching nuts.
• Precise 0.1" travel per revolution enables controlled linear movement ideal for positioning tables, lifts, and adjusting mechanisms.
• Full RoHS 3 and REACH compliance ensures environmental responsibility and meets global regulatory standards for industrial components.
• 6-foot length with single-start threading provides extended reach with consistent pitch for uniform motion transmission.

Professional Applications & Engineering Value

This left-hand Acme lead screw solves critical engineering challenges in motion control systems where standard right-hand threads are unsuitable. The 1018 Carbon Steel composition delivers the perfect balance of machinability and strength, resisting deformation under continuous operation. With its Class 2C thread fit and ±0.009" per foot accuracy, this component eliminates positioning errors in CNC equipment, industrial automation, and precision manufacturing setups. The fully threaded, single-start design ensures consistent engagement with mating nuts, making it ideal for applications requiring reverse-thread functionality in clamping systems, adjustable platforms, and specialized machinery where directional control is paramount.

Specification Summary & Compliance

This 1/2"-10 Acme lead screw maintains Class 2C thread fit tolerances as per industry standards, delivering precise travel distance of 0.1" per turn with accuracy within ±0.009" per foot. Manufactured from 1018 Carbon Steel with tensile strength rated at 64,000 psi and Brinell 126 hardness. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety standards for industrial applications worldwide.
