Professional Applications & Engineering Value

This M18 coupling nut delivers critical engineering solutions for heavy-duty fastening applications where extended thread engagement is required. Manufactured from black-oxide steel, the component provides enhanced corrosion protection while maintaining the mechanical properties necessary for structural connections. The fully threaded design and coarse metric threading (2.5 mm pitch) enable rapid assembly and disassembly in maintenance-intensive environments, while the Class 6H thread fit ensures precise mating with corresponding male threads. The external hex drive profile allows for high-torque installation using standard tools, making it ideal for construction equipment, machinery frames, and industrial structures where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This coupling nut features M18 x 2.5 mm metric coarse threads with Class 6H thread fit tolerance, manufactured to DIN 6334 and ASME B18.2.2 standards. The component maintains dimensional accuracy with 27 mm width across flats and 54 mm length. Quality assurance includes compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, with mechanical performance certified to Class 8 strength grade for industrial fastener applications.
