Schnorr Safety Washers Applications

The original SCHNORR® safety washers were developed as a reliable and economic bolt locking device with the basic principle of a disc spring. This ingenious form combines the advantage of security through friction and mechanical locking.
Original SCHNORR® safety washers are now used worldwide where secure fastening connections to counter the effect of vibration are required.

Functional Principle

SCHNORR® safety washers are in the form of a disc spring but with a trapezoidal cross-section and serrations on both sides. The outer diameter is matched to the head diameter of the pan head and socket head cap screws.

Schnorr Disc Springs Features

Original SCHNORR® Disc Springs

The characteristic benefits of original Schnorr® disc springs include:

Load deflection curves of straight, progressive or degressive character according to the selection of spring arrangement and dimension.
Simple adjustment of the spring stack length by the addition or removal of individual springs, thus altering the spring stack characteristic.
Efficient use of space with high spring forces obtainable with small deflections.
Largely self-damping, particularly with parallel stacking.
No setting or fatigue under normal loads load.
Long service life
Flexibility in applying the disc springs can reduce stock levels.

By means of these characteristics, the original SCHNORR® disc spring has developed such a wealth of application areas that nowadays there is scarcely an engineering area where it is not used.

Schnorr Safety Washers Features

The Original SCHNORR® Safety Washers offer the following advantages.

High resistance to vibration due to positive locking of the serrations.
Concentrical force transmission and uniform axial load eliminate bending torques and deformation of the bolt stem.
The design of the serrations prevents friction and damage to components when tightening.
Extremely high safety against loss of pretension force and loosening.
Wide variety of materials and different finishes.
The closed ring form results in a high degree of pretensioning, while avoiding burst-open effect.
Development and design of the washers take place based on the screw geometrics, tightening torque as well as the constructive circumstances.
Also applicable for clearance holes (safety washer is necessary on both sides)
Applicable for elongated holes (using type VS)
Equivalent locking effect like wedge-locking washers (according to vibration test DIN 65101 resp. DIN 25201-4 Part B)
