AET serrated disc washer for DIN 912 bolts

AET serrated disc washer for DIN 912 bolts

The AET washer was designed specifically for applications where the
outer diameter of the washer cannot exceed that of the bolt head.
Thanks to the conical form of this washer, the tightening torque is spread
evenly in all applications. The serrated surfaces are incrusted into the head
of the bolt or screw and also into the surface of the part which is being
fastened, forming an immobile unit resistant to loosening if subjected to
vibration.
This washer is suitable for use with a wide range of screws and bolts. It is very
useful for use in mechanical assemblies where a locking function is essential. The
elasticity of this washer compensates for axial forces avoiding lateral movement and
unwanted grating noises.
The AET washer is particularly recommended for use for bolts manufactured according to DIN 74 and DIN 912 due to the perfect fit.
