Loosening torque
KMFE lock nuts are held in place on a shaft (sleeve) by friction. The amount of friction can vary, depending on the amount of torque applied to the grub (set) screw (locking screw) during installation, the surface finish of the shaft (sleeve) thread, the amount of lubricant on the thread, etc. The lock nuts should be properly installed and there should be only a limited amount of lubricant on the thread.

KMFE lock nuts provide sufficient locking for intended bearing applications.
