schnorr German disc spring anti-loosening washers are used for locking bolt and screw connections. They can be used for medium or high-strength bolt and screw connections.schnorr German disc spring anti-loosening washers consist of two disc springs. The outer side features radial cams, and the inner side features inclined teeth. The working principle is very simple: during assembly, the inner inclined tooth faces oppose each other, while the outer radial cam faces engage with the contact surfaces at both ends. When the connected components are subjected to vibration and the bolt tends to loosen, only relative sliding between the inner inclined tooth faces of the two washers is allowed, generating lifting tension, thereby achieving a 100% locking effect. schnorrDisc springwashers can be applied in all strong vibration environments. Original schnorr anti-loosening safety washers are a reliable and economical bolt locking device developed based on the basic principles of disc springs, resisting the effects of vibration through secure fastening connections. This clever design combines the safety advantages of friction and mechanical locking. schnorr German disc spring anti-loosening washers are widely used worldwide, ranging from automotive engineering to machining, cement, and plant engineering. Additionally, safety washers can be used in lawn mowers, textile machines, machine tools, pneumatic drills, the steel industry, etc.

schnorr German disc spring anti-loosening washers Structure: Disc spring type, with a trapezoidal cross-section and serrations on both sides. The outer diameter matches the head diameters of pan head and hex socket head screws.Due to the conical shape, optimal traction force can be obtained in the maximum positive locking state.schnorr German disc spring anti-loosening washers Features: 1). High vibration resistance due to reliable locking by the serrations. 2). The disc spring design ensures concentric force transmission and uniform axial load, eliminating bending torque and deformation of the bolt. 3). The serration design prevents friction and damage to components during tightening. 4). Extremely high safety against loss of preload and loosening. 5). Available in various materials and different finishes. 6). The closed-loop form results in high preload while avoiding the bursting open effect. 7). The development and design of the washers are based on the screw geometry, tightening torque, and construction conditions.

schnorr German disc spring anti-loosening washers Assembly requirements

schnorr disc spring washers are characterized by simple installation.

1). Simply place the two washers with their inner inclined tooth faces opposing each other between the nut and the connected material;

2). After the nut is tightened, the outer radial cam faces of the disc spring washers engage with the contact surfaces at both ends, and the angle of the slope on the inner inclined tooth faces of the disc spring washers is greater than the thread angle of the bolt;

3). When the bolt is elongated due to mechanical vibration, the nut will rotate and loosen accordingly. Since the friction on the outer radial cam faces of the anti-loosening washers is greater than the friction between the inner inclined tooth faces, in this state, only relative sliding between the inner inclined tooth faces is allowed, subsequently generating a certain lifting tension;

4). When the bolt contracts, the inclined toothed surfaces of the disc spring washers return the nut to its original position. This achieves a 100% anti-loosening and locking effect;

5). Disc spring washers are suitable for relatively flat and smooth surfaces;

6). If the connected material is non-metallic, a metal plate can be fixed to the connected material, allowing the use of disc spring washers;

7). A torque wrench is not required when installing disc spring washers;

8). Pneumatic tools may be used when installing or removing disc spring washers.
