S-98940A324 5/8"-10 x 6 ft. Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Exceptional wear resistance from hardened 4140 alloy steel construction with black-oxide coating for corrosion protection in demanding environments
• Precise motion control with ±0.009" per foot accuracy and consistent 0.1" travel distance per revolution for reliable positioning
• Superior load-bearing capability thanks to 125,000 psi tensile strength and Brinell 271 hardness for heavy-duty applications
• Optimized thread engagement with Class 2C thread fit ensuring smooth operation and reduced backlash in precision assemblies
• Left-hand threading advantage providing counter-rotational motion solutions where standard right-hand threads are unsuitable
• Full-length threading enabling continuous engagement and maximum utility across the entire 6-foot length
• Environmental compliance with RoHS 3 standards for use in regulated industries and international markets

Professional Applications & Engineering Value

This left hand Acme lead screw delivers critical performance in applications requiring reverse-thread functionality and precision linear motion. The black-oxide 4140 alloy steel construction, combined with hardening treatment, provides exceptional durability against wear and corrosion in industrial environments like CNC machinery, automated positioning systems, and material handling equipment. The Class 2C thread fit ensures minimal play and consistent performance in high-load scenarios, while the 0.1" travel per turn offers predictable movement for precision control systems. Engineers specify this fully threaded Acme screw for applications where standard right-hand threading cannot provide the required counter-directional motion, making it ideal for specialized manufacturing, packaging machinery, and custom automation solutions requiring reliable, long-lasting linear drive components.

Specification Summary & Compliance

This precision Acme lead screw features 5/8"-10 left-hand threading with Class 2C thread fit per inch system standards, ensuring proper clearance for smooth operation. The component delivers 0.1" travel distance per turn with accuracy maintained within ±0.009" per foot. Manufactured from hardened 4140 alloy steel with black-oxide surface treatment, it achieves 125,000 psi tensile strength and Brinell 271 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) environmental standards for use in regulated industrial applications worldwide.
