Professional Applications & Engineering Value
Engineered for heavy-duty coupling applications, these M16 coupling nuts solve critical connection challenges in structural assemblies, machinery framing, and extended fastener systems. The zinc-plated steel construction provides essential corrosion protection where environmental exposure threatens joint integrity, while the Class 10 strength rating ensures maintained clamping force under vibration and dynamic loads. The fully threaded metric design with 2mm coarse pitch enables rapid assembly and adjustment, particularly valuable in construction, manufacturing, and equipment maintenance where reliable threaded connections must withstand continuous operational stress without compromising performance or safety standards.
Specification Summary & Compliance
This coupling nut features precise M16x2mm coarse thread with Class 6H thread fit tolerance, manufactured to DIN 6334 standards for dimensional consistency. The component maintains 24mm width and 48mm length specifications with external hex drive configuration. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, ensuring adherence to international regulatory requirements for hazardous substance restrictions.
