DIN 137 A 4 Form B Spring washers Form B = corrugated (reduced spring force) Dimension: B 10



The use of the following safety elements is ineffective:

• Spring washers DIN 127 and DIN 128, as well as spring washers DIN 137.

These standards have no securing effect on screw connections

of higher strength (from 5.6) because they are simply flattened

and cannot compensate for any settlement.

• Serrated lock washers DIN 6798 (Palnuts)



All of these products do not meet the security requirements. The norms became. taking into account the state of the art, withdrawn.
