DIN EN 1663 Lock Nuts

The superior anti-vibration performance of the DIN EN 1663 lock nut: when the thread is tightened, the crest thread of the bolt tightly enters the 30° wedge-shaped slope of the din lock nut and is clamped, and the normal force exerted on the wedge-shaped slope is the same as the bolt's normal force. The axis forms an included angle of 60° instead of 30°. Therefore, the normal force generated when the DIN EN 1663 nut and lock nut is tightened is much larger than that of the ordinary standard nut. Moreover, the DIN EN 1663prevailing m20 lock nut also has a great anti-loose and anti-vibration ability.
