Product Name : GUK Self Locking Nuts
Product Description

What Is GUK Self Locking Nut?

GUK self locking nuts are self-locking due to their nylon PA6 insert. 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 according to DIN 981.

How GUK Nuts Work?

GUK self locking nuts add a nylon insert that sits on top of the nut to deform on 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.

In addition to the nylon PA6 self-locking feature, GUK self locking nuts are equipped with four equally spaced grooves on the outside diameter of the nut, which allow a hook wrench to easily tighten or loosen the nut. These self-locking nuts are not suitable for high temperature over 100 degree applications.
