Features

DIN6796 Heavy Duty Bolting Washer has been specially developed for high-strength bolts of grades 8.8-12.9. This represents the most powerful form of safety washer in the form of a disc spring. The load of the washers has been matched to these bolts and is 70 to 90% of the bolt load in the flat state. These Heavy Duty Bolting Washers conform to DIN6796, and are designed for high demands on the protection of bolt joints. As a highly progressive load increase occurs at the end of the spring deflection when the washer is flattened the load has been indicated as double the calculated value. Tests have shown that these values are comparable with the measured value. The characteristic features of DIN6796 Heavy Duty Bolting Washer: ·High axial load ·Optimum compenstation for setting in the joint ·Reduction of the dynamic loading of the screw ·Uniform concentric loading and high safety through a high degree of spring action ·Suitable for captive fitting on a wide range of bolts
