Original Locking Washer
The DISC-LOCK Washer,
specifically designed to solve the problem of fastener
failure, is a heavy duty structural self-locking product,
which prevents loosening caused by shock or vibration in
high stress applications. It is probably the most effective
locking device for maintaining joint integrity in the world.
How does the DISC-LOCK Washer
work?
The working principle behind
the DISC-LOCK Washer is simple. It consists of two
washer-shaped pieces, which have inclined cams on one side
and a series of ridges on the other. On installation the two
cam sides are mated together and placed between the nut and
the joint material. Under vibration the nut will attempt to
rotate loose but, as the angle of the cams is greater than
the pitch angle of the thread on the bolt, the interlocking
cams and the non-slip ridges of the DISC-LOCK Washer work
together to create a jamming effect. This effect prevents
loosening and further locks the assembly, thereby
maintaining joint integrity.
The DISC-LOCK Washer is not only a vibration-proof locking
device but also a heavy duty structural locking device
recommended for the most stressful applications.
