SSAP Lock Washers

How do they work?

Each washer has an inclined cam on one side and seizing ridges on the other. The
two cam sides are mated together, and because the angle of the cams is greater than
the pitch angle of the thread, the cams and the ridges work together to create a
jamming effect. This effect prevents loosening and locks the assembly.

To Install …

Mate the cam sides together.

When the two cam sides are mated correctly, it is difficult to rotate the washers in a clock-wise direction.
