GUK self locking nuts provide secure locking without the need for additional locking mechanisms or tools because they add a nylon insert that sits on top of the nut to deform the mating thread and catch the bolt or stud. This provides a locking function that creates resistance - or primary torque - to lock the nut in place and resist vibration. Therefore, they can also be used as retaining nuts and can be used multiple times. The thread series mainly corresponds to cylindrical bearing slotted lock nuts
Beyond their nylon PA6 self-locking attribute, GUK self locking nuts feature four equally spaced grooves on the outer diameter. These grooves enable easy tightening or loosening of the nut using a hook wrench.
