S-6350K683 1/4"-40 x 1" Ultra-Precision Lead Screws and Nuts

Key Features & Benefits at a Glance

• Ultra-precise positioning with consistent 0.025" travel per turn for repeatable motion control in precision applications
• Excellent corrosion resistance and low friction operation thanks to durable Acetal Plastic construction
• Simplified installation with integrated flange design featuring three 9/64" mounting holes for secure attachment
• Smooth, reliable performance achieved through rounded Acme thread profile that reduces wear and binding
• Robust load handling with 50 lbs dynamic thrust capacity and 9000 psi tensile strength for demanding applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global industrial use
• Reduced maintenance requirements due to self-lubricating properties of Acetal Plastic material

Professional Applications & Engineering Value

This 1/4-40 Acetal Plastic Flange Nut delivers exceptional value in ultra-precision lead screw systems where accuracy and reliability are paramount. The rounded Acme thread profile minimizes friction and prevents jamming in high-cycle applications, while the Acetal Plastic construction provides natural lubrication that eliminates the need for external lubricants in sensitive environments. The integrated flange design with three mounting holes ensures secure positioning without additional hardware, making it ideal for precision equipment in medical devices, laboratory instruments, and optical positioning systems where 0.025" travel per turn accuracy is critical. The material's inherent corrosion resistance makes it suitable for cleanroom and chemically challenging environments where metal components would degrade.

Specification Summary & Compliance

This precision flange nut features 1/4"-40 right-hand rounded Acme threads with standard inch system tolerances. The component maintains 9000 psi tensile strength and 50 lbs dynamic thrust load capacity with dimensions including 1" length, 1/2" diameter, and 1" flange diameter with 3/16" thickness. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for global industrial applications requiring strict regulatory compliance.
