• Superior wear resistance and longevity thanks to the wear-compensating spring that maintains thread engagement and reduces maintenance needs.
• Lightweight and corrosion-resistant design using durable Acetal Plastic material, ideal for applications requiring low friction and chemical stability.
• Easy and secure mounting with 3 pre-drilled mounting holes and integrated flange, simplifying installation and improving system stability.
• High tensile strength of 9700 psi ensures reliable performance under dynamic loads in demanding industrial environments.
• Optimized for precision motion control with rounded Acme right-hand threads, providing smooth, backlash-free operation in fast-travel lead screw assemblies.
• Compliance with global standards including RoHS 3 and REACH, ensuring environmental safety and regulatory acceptance for international projects.

Professional Applications & Engineering Value

This 3/8-8 Acetal Plastic Flange Nut is engineered to address common challenges in fast-travel precision lead screw systems, such as wear-induced backlash and speed limitations. The Acetal Plastic construction offers excellent dimensional stability and low moisture absorption, reducing the risk of seizing or degradation in humid conditions. Its rounded Acme thread design minimizes friction, allowing for smoother motion and higher travel speeds without sacrificing accuracy. The integrated wear-compensating spring automatically adjusts for thread wear, extending service life and maintaining precise positioning in applications like CNC machinery, automated packaging equipment, and medical devices. This nut supports dynamic thrust loads up to 10 lbs, making it a reliable choice for linear motion systems that demand both speed and durability.

Specification Summary & Compliance

The nut features a 3/8"-8 rounded Acme thread with right-hand direction, ensuring compatibility with standard lead screws. Key dimensions include a 1 29/32" length, 0.703" diameter, and flange diameter of 1 1/2" with three 13/64" mounting holes for secure attachment. It adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of hazardous substances and suitable for use in regulated industries. The tensile strength of 9700 psi and dynamic thrust load capacity of 10 lbs are verified, supporting consistent performance in precision engineering applications.
