Description
This castle nut is used for securing and locking a wheel bearing on the axle of a boat trailer. After adjusting the bearing, the castle nut is secured with a cotter pin to prevent the nut from loosening while driving.
The castle nut is available in a standard version and a version with a flange for ECO hubs. The flanged version provides a larger contact surface and is suitable for applications where an ECO hub is used.
