DIN 6797 Toothed Lock Washers
Jiaxing Aoke is a Chinese factory to produce DIN6797 toothed lock washer, our factory has obtained ISO9001 certificate. DIN6797A external toothed lock washers and DIN6797J internal toothed lock washers are the most commonly used during assembly. The function of the DIN 6797 toothed locking washer is to prevent the threads from loosening due to vibration and impact. DIN 6797 series lock washers are non-spring self-locking washers. Their core locking principle is achieved through precision-machined serrations on the washer surface, rather than elastic deformation. The working principle of the DIN6797 toothed washer is that when the bolt or nut is tightened, the DIN6797 teeth lock washer is forced to generate pressure, and the bite effect of the serrations prevents the thread from loosening d......
