Professional Applications & Engineering Value

This female hex thread adapter is engineered to solve critical connectivity challenges in metric-to-metric assemblies, particularly where equipment or components feature mismatched thread sizes (M3.5 to M4). The 18-8 Stainless Steel construction provides excellent resistance to corrosion, oxidation, and chemical exposure, making it ideal for demanding sectors like automotive, electronics, machinery, and industrial automation. The external hex drive and precise Class 6H thread fit ensure secure, tool-accessible installation, reducing the risk of cross-threading and thread damage during repeated use. By offering high tensile strength and hardness, this adapter maintains joint integrity in high-vibration or load-bearing applications, enhancing assembly longevity and reducing downtime for maintenance or part replacement.

Specification Summary & Compliance

The adapter features Class 6H thread fit on both M3.5 (0.6mm pitch, 9.5mm length) and M4 (0.7mm pitch, 11.1mm length) sides, ensuring dimensional accuracy per ISO metric standards. It conforms to ASTM A582 for material and manufacturing specifications, and is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, confirming its suitability for use in regulated and environmentally conscious industries.
