Nord-Lock washers secure bolted joints with tension instead
of friction. The system is comprised of a pair of washers with
cams on one side and radial teeth on the opposite side.
Since the cam angle ‘α’ is greater than the thread pitch ‘β’
a wedge effect is created by the cams, preventing the bolt
from rotating loose.
The proven
original
Nord-Lock wedge-locking products are the ideal choice
for critical bolted joints.
