Safety Washers

The SCHNORR® safety washers can be made from different materials and can be supplied with different surface treatments.

Materials with the highest tensile strength and utmost elasticity are required to make disc springs. Materials for disc springs are principally supplied in the following forms:

• Original SCHNORR® Safety Washers “S”
  • The Original SCHNORR® Safety Washer “S” is suitable for normal requirements and available for screws from M1,6 to M36. Other sizes as well as customized dimensions can be inquired for.
• Original SCHNORR® Safety Washers “VS” with greater thickness
  • The Original SCHNORR® Safety Washer “VS” can be used with high-strength bolts of the grade 8,8 without any restrictions.
  • This strengthened safety washer has a greater thickness and for this reason achieves higher pre-tensioning loads.
  • The outside and the inside diameter as well as the toothing correspond to the type “S”. It can be delivered for screws M5 to M3.
  • Special sizes are also available upon request.
