DIN 6334 Class 6 Specifications

Engineered for Metric Threaded Assemblies

DIN 6334 Class 6 coupling nuts are designed with an extended hex body to ensure full thread engagement and proper load distribution.

• Standard: DIN 6334

• Strength Class: Class 6

• Thread Type: Metric coarse internal threads

• Sizes: Common metric diameters from M6 through M30

• Design: Long hex profile for secure alignment and torque control

The extended length allows two male-threaded fasteners or rods to be joined securely, making these coupling nuts ideal for threaded rod extensions and adjustable assemblies.

Clear Cr3 Zinc Plating Benefits

Corrosion Resistance with Environmental Compliance

Clear Cr3 (trivalent chromium) zinc plating provides effective corrosion protection while meeting modern environmental standards.

• Protects against rust and oxidation in mild to moderate environments

• RoHS- and REACH-compliant alternative to hexavalent chromium

• Clean, bright finish for professional appearance

• Smooth surface improves thread engagement and installation

This plating makes the coupling nut suitable for indoor use and light outdoor exposure where long-term reliability is required.
