S-6350K213 3/8"-40 x 1 29/32" Ultra-Precision Lead Screws and Nuts

Key Features & Benefits at a Glance

• Extended service life through the wear-compensating spring that maintains consistent performance by automatically adjusting for thread wear.
• Corrosion and chemical resistance provided by the durable Acetal Plastic material, ideal for harsh environments without risk of rust.
• Precise linear motion control with a consistent 0.025" travel per turn, ensuring repeatable accuracy in ultra-precision applications.
• Simplified installation and secure mounting with a 1 1/2" flange diameter and three pre-drilled mounting holes for stable integration.
• Reliable load handling with a 10 lbs dynamic thrust load capacity, suitable for controlled, low-friction movements.
• Smooth, low-backlash operation due to the rounded Acme thread form and single thread start, enhancing motion smoothness.
• Global regulatory compliance with RoHS 3 and REACH standards, ensuring safety and environmental responsibility for international projects.

Professional Applications & Engineering Value

This 3/8-40 Acetal Plastic Flange Nut is engineered to solve critical challenges in ultra-precision lead screw systems, such as backlash, wear, and corrosion. The wear-compensating spring technology actively counteracts thread degradation, maintaining precision over extended cycles—vital for applications in medical devices, laboratory automation, and optical positioning equipment. Made from Acetal Plastic, it offers inherent lubrication and resistance to moisture and chemicals, eliminating the need for external lubricants and reducing contamination risks. Its right-hand rounded Acme thread ensures smooth, efficient motion transfer with minimal friction, while the integral flange with three mounting holes provides robust, vibration-resistant attachment. This nut delivers long-term reliability and accuracy in demanding B2B industrial settings.
