S-6350K685 1/8"-41.7 x 6" Ultra-Precision Lead Screws and Nuts

Key Features & Benefits at a Glance

• Ultra-precise positioning with ±0.0006" per inch travel accuracy for reliable, repeatable linear motion in critical applications.
• Exceptional durability and corrosion resistance provided by 303 Stainless Steel construction, ensuring long service life in demanding industrial environments.
• High mechanical strength with a 90,000 psi tensile strength and Brinell 160 hardness to withstand significant loads without deformation.
• Smooth and efficient motion transfer due to the rounded Acme thread profile, which reduces friction and wear compared to square threads.
• Ready for immediate integration as a fully threaded, 6-inch long component with a single-start, right-hand thread for straightforward assembly.
• Consistent 1:1 speed ratio and 0.024" travel per turn for predictable and easily calculable linear displacement.
• Global compliance and environmental safety, meeting RoHS 3 and REACH standards for use in regulated markets and sustainable manufacturing.

Professional Applications & Engineering Value

This ultra-precision lead screw is engineered to solve critical challenges in precision linear motion control. The 303 Stainless Steel material offers excellent machinability and corrosion resistance, ideal for medical devices, laboratory automation, and optical equipment where contamination and failure are not an option. The rounded Acme thread design minimizes backlash and provides smoother operation than square threads, enhancing the lifespan of both the screw and its mating nut. With its ±0.0006" per inch accuracy, this component eliminates positioning errors in high-resolution applications, ensuring that your machinery operates with the repeatability required for advanced manufacturing and testing processes.
