Our DIN 6331 collar nuts have been specially developed for the requirements of machine, device and tool construction. Thanks to the integrated collar surface (flange), these nuts offer an enlarged contact surface that optimally protects the component and evenly distributes the forces that occur. In combination with a high strength class, they are ideal for friction-locked connections with high tightening torques.
