  • Durable performance under heavy loads thanks to the coarse M36x4mm thread, providing excellent grip and vibration resistance.
  • Precise dimensional compliance with DIN 6334 standards, ensuring consistent quality and interchangeability in metric systems.
  • Enhanced safety and environmental compliance by meeting RoHS 3 regulations, suitable for regulated industrial applications.
  • Optimized for extended rod or bolt joining with a 108mm length and 55mm width, offering versatility in long-span assemblies.

Professional Applications & Engineering Value

This M36 coupling nut is engineered from zinc-plated steel to address common challenges in heavy-duty fastening, such as corrosion and mechanical stress. Its fully threaded, right-hand metric thread design with a coarse pitch ensures quick alignment and robust load distribution, making it ideal for connecting long rods or bolts in construction, machinery, and automotive frameworks. The external hex drive allows for straightforward torque application, reducing assembly time while maintaining Class 6H thread fit precision to prevent cross-threading and ensure leak-proof joints in high-vibration environments. By complying with DIN 6334, it delivers reliable performance in metric-based systems, enhancing structural integrity and minimizing maintenance needs in industrial applications.

Specification Summary & Compliance

This coupling nut features a Class 6H thread fit with ISO-compliant tolerances for precise engagement, fully threaded M36x4mm coarse metric threads, and adherence to DIN 6334 manufacturing standards. It is RoHS 3 (2015/863/EU) compliant under exemption 6(a)-I, ensuring environmental safety for industrial use without compromising on lead alloy requirements in steel.
