Vargal® lock nuts are designed for applications in which a reliable anti-loosening performance is critical. When tightened, the external spring is radially deformed and pressed against the nut collar which results in a reliably locked connection of the assembled parts. Operators can apply normal tools for the assembly, as a low torque is enough to reach the desired locking effect. Even after multiple uses the anti-loosening performance is not reduced.
