Also often used with self-tapping screws DIN 571 and threaded studs DIN 975 when installing wooden structures. A characteristic feature of this washer is that the outer diameter is equal to 3rd of the inner diameter, which helps to take these parameters into account during calculations and installation.

Material high-strength structural alloy steel.
