Professional Applications & Engineering Value
This M5 to M4 female hex thread adapter solves critical challenges in industrial assembly where metric thread adaptation is required between different component sizes. The zinc-plated steel construction provides essential corrosion protection for machinery operating in humid or outdoor environments, while the Class 6H thread fit maintains precise tolerances to prevent loosening under vibration. With a 78,000 psi tensile strength and Rockwell B85 hardness, this adapter withstands high mechanical stresses in automotive, manufacturing, and equipment maintenance applications. The 10mm hex drive facilitates quick installation in confined spaces, making it ideal for production lines and field service where downtime reduction is critical.
Specification Summary & Compliance
This adapter features Class 6H thread fit on both M5 (0.8mm pitch) and M4 (0.7mm pitch) female threads, ensuring dimensional accuracy per metric standards. Manufacturing complies with ASTM A108 and ASTM B633 specifications for material and plating quality. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(a)-I for lead as an alloying element in steel, meeting international environmental regulations for industrial components.
