Materials for the manufacture of washers DIN 6797 A
Lock washers DIN 6797 A are made of the following materials:
- Steel, which can optionally be plated with zinc. Zinc (Plated) protects against corrosion if the fastener is to be used in aggressive environments.
- Stainless steel. Steel grade A2 allows the fasteners to be used at significant temperature drops and in aggressive and humid environments.
