Professional Applications & Engineering Value

This female hex thread adapter is engineered to solve common challenges in metric-to-metric thread adaptation, such as mismatched connections and vibration-induced loosening. The aluminum body offers an optimal balance of strength and weight reduction, ideal for aerospace, automotive, and electronics assembly where every gram counts. With a Class 6H thread fit on both M8 and M3.5 ends, it ensures tight tolerances that resist wear and prevent fluid or pressure leaks in hydraulic and pneumatic systems. The external hex drive design allows for quick tool engagement, reducing installation time in high-volume production lines. By maintaining precision thread standards, this adapter minimizes downtime and enhances the reliability of your equipment in harsh operational conditions.

Specification Summary & Compliance

The adapter features Class 6H thread fit for both M8 x 1.25 mm and M3.5 x 0.6 mm threads, ensuring high dimensional accuracy per ISO metric standards. It complies with RoHS 3 (2015/863/EU) under exemption 6(b) for lead as an alloying element in aluminum, supporting environmental and safety regulations. Manufacturing adheres to consistent metric system measurements, with specified thread lengths of 16 mm (M8 end) and 9.5 mm (M3.5 end) for reliable performance in industrial adaptations.
