As a pioneer of the disc spring application, Adolf Schnorr founded the family-owned company in 1908. Today, after more than 100 years of company history, SCHNORR® has grown into a leading manufacturer of top quality specialized parts as well as standard ribbed lock washers and bolt locking systems globally. Besides its long-lasting experience and high degree of development competence in stamping and turning, SCHNORR® now also offers technology of fineblanking, manufacturing know-how of distortion of critical disc springs and an additional product group – the wave spring.


  • Con-centrical force transmission and uniform axial load eliminate bending torques and deformation of the bolt stem
  • The closed ring form results in high degree of pre-tensioning while avoiding burst-open effect
  • The design of the serrations prevents friction and damage to components when tightening and therefore creating high resistance to vibration due to positive locking of the serrations
