Our innovative design allows for two identical nuts to be tightened onto the same bolt. By applying a specific tightening torque between the two nuts, you will achieve a strong and dependable bolt connection. Each nut features staggered cams, and the internal wedge design has a slope angle greater than the bolt's nut angle, enabling the nuts to grip securely together. During vibrations, the protruding parts of the anti-loosening nuts work against each other to create lifting tension, effectively preventing any unintentional loosening.
