Metric Hex Coupling Nuts, Class 6, Zinc Cr+3
Metric Hex Coupling Nuts Class 6 Zinc Cr+3 are precision-engineered fasteners used to join two pieces of threaded rod or other male-threaded components in metric assemblies. Manufactured to meet ISO and DIN standards, these coupling nuts feature a hexagonal body for easy wrenching and consistent torque application. The Class 6 strength rating provides dependable tensile performance for light to medium-duty applications. The Zinc Cr+3 (trivalent chrome) finish offers enhanced corrosion resistance and a clean, bright appearance suitable for indoor and mildly corrosive environments.
Designed for versatility and reliability, Class 6 Metric Hex Coupling Nuts with Zinc Cr+3 plating provide secure thread engagement and rust protection for general-purpose use in machinery, construction, and equipment assembly. The zinc plating with trivalent chromium ensures environmental compliance and improved durability compared to traditional coatings. Ideal for connecting threaded rods or extending fastener reach, these coupling nuts deliver precise alignment and consistent performance in a wide range of metric fastening applications.
