Toothed lock washers

　　made of steel

　　for screw-locking devices

　　Additional item for the screw-locking device for high 

　　bolt forces!

　　In combination with the well-known screw-locking 

　　device made of polyamide, the toothed lock washer 

　　made of steel is a valuable further development for the 

　　use of bolts made of high-grade steel. This combination 

　　permits any desired bolt force without damaging the 

　　screw-locking device as a result of subjecting the

　　bolt and nut to high stress.

　　During the assembly procedure, the locking device is 

　　placed in the toothed lock washer. When the nut is 

　　being tightened, the locking device becomes deformed, whereby the external reinforcement of the crosssectional double-T-shaped locking device is pressed 

　　against the extemal wall of the toothed lock washer

　　which then prevents further evasion toward the outside. The internal reinforcement is pressed under high 

　　pressure into the threads of the bolt which results in 

　　high frictional locking and simultaneous sealing. Due 

　　to the combination of the screwlocking device and the 

　　toothed lock washer, a high coefficient of friction is 

　　created between the supporting surface and the nut

　　when these parts are tightened down. This also increases the locking effect considerably. At the places 

　　where the teeth of the toothed lock washer are located, the locking device is perforated under high pressure so that the nut comes into contact with the steel 

　　teeth. The result is a partially rigid connection of steel 

　　on steel and plastic that is capable of absorbing any 

　　desired bolt force. Due to the material of the screwlocking device pressed into the semicircular recesses 

　　of the toothed lock washer, a longlasting elastic effect 

　　is provided
