Professional Applications & Engineering Value

This M8 metric flange nut is engineered from Acetal Plastic to address common challenges in ultra-precision linear motion systems, such as minimizing friction and wear in high-cycle applications. Its rounded trapezoidal thread design ensures smooth travel at 1.5 mm per turn, reducing backlash and enhancing positional accuracy in CNC machinery, medical devices, and automated equipment. The material's inherent corrosion resistance and low moisture absorption make it suitable for environments where metal components would degrade, while the flange design with three mounting holes provides secure attachment, preventing loosening under dynamic loads. By offering a lightweight yet durable alternative to metal nuts, it helps extend equipment lifespan and maintain consistent performance in temperature-varying settings from -40° to 185° F.

Specification Summary & Compliance

This nut features an M8 x 1.5 mm metric trapezoidal thread with right-hand direction and standard pitch for precise engagement. Key dimensions include a 0.548" diameter, 1 1/8" flange diameter, and 3/16" flange thickness, with three 9/64" mounting holes on a 7/8" bolt circle. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring adherence to environmental and safety regulations. The component is designed for general precision use, with a dynamic thrust load capacity of 75 lbs and a tensile strength of 8000 psi, though hardness is not rated for specific industrial standards.
