For improved vibration resistance, the curved, spring-like washer adheres to surfaces more firmly than tooth-lock washers. Because you can manually twist these locknuts into position, they also install just as rapidly. Use a wrench or socket to tighten the nut once it is against your material. Unlike teeth, the washer's smooth edges won't scratch the surface. These locknuts are reusable as long as the washer remains in place.
These locknuts are almost half as robust as medium-strength steel nuts and are rated Grade 2, Class 6, or lower. In order to prevent thread stripping during installation, use them with screws that have a comparable strength grade.
The majority of machinery and equipment can be fastened with these Grade 5 or Class 8 nuts. Make sure your screw has a similar strength rating to prevent stripped threads during installation.
