External Tooth Keps Locknuts
Click image to enlarge
Metric and standard external tooth locknuts appear very different from the other locknut parts; however, they too are utilized for special locking features. These locknuts offer external teeth that surround the perimeter of the nut to grip into the mating surface. The teeth provide additional surface area to improve load distribution and minimize stress. As with serrated flange locknuts, external tooth locknuts may cause damage to soft surfaces if over tightened. It’s critical to ensure that installation is completed properly to the appropriate torque.
