Professional Applications & Engineering Value

This M30 coupling nut delivers exceptional engineering value in demanding industrial applications where reliable threaded connections are critical. Manufactured from zinc-plated steel, it provides superior corrosion protection for construction equipment, machinery frames, and structural assemblies exposed to environmental elements. The fully threaded design with coarse metric threading ensures maximum thread engagement across the entire 90mm length, distributing load forces evenly to prevent stress concentration. The external hex drive profile allows for high-torque installation using standard tools, making it ideal for applications requiring frequent adjustments or maintenance. With DIN 6334 certification and Class 8 strength rating, this coupling nut maintains integrity under extreme vibration and dynamic loads common in heavy machinery, conveyor systems, and industrial framework connections.

Specification Summary & Compliance

This coupling nut features precise metric threading with M30×3.5mm dimensions and Class 6H thread fit tolerance according to ISO standards. Manufacturing complies with DIN 6334 specifications for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations regarding chemical safety. The zinc-plated steel construction combined with Class 8 strength classification ensures reliable performance in industrial fastening applications requiring high mechanical properties and environmental resistance.
