Serrated safety washers can be made from different materials and can be supplied with different surface treatments.

Safety Washer "S" is suitable for normal requirements and available for screws from M 1,6 to M 36. Other sizes as well as customized dimensions can be inquired for.

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.
