Professional Applications & Engineering Value
This metric-to-metric female hex thread adapter solves critical connectivity challenges in industrial equipment, automation systems, and precision machinery. The black-oxide steel construction provides essential corrosion protection for harsh environments while maintaining dimensional stability. With Class 6H thread fit precision, engineers can eliminate cross-threading issues and achieve reliable connections between M5 and M4 components in hydraulic systems, motor mounts, and assembly fixtures. The external hex drive design ensures maximum torque application during installation, reducing assembly time while preventing fastener damage. This heavy-duty adapter maintains structural integrity under continuous vibration and load variations, making it ideal for manufacturing equipment, automotive applications, and industrial machinery where metric thread adaptation is required.
Specification Summary & Compliance
This precision adapter features M5 x 0.8mm to M4 x 0.7mm metric thread conversion with Class 6H thread fit tolerance for both ends, ensuring precise engagement. Manufacturing complies with ASTM A108 specifications for material quality and performance. The adapter is RoHS 3 (2015/863/EU) compliant with exemption 6(a)-I for lead as an alloying element in steel, meeting international environmental standards. Thread lengths of 12.7mm (M5) and 11.1mm (M4) provide sufficient engagement depth for secure connections in industrial applications.
