GUK Nylon Insert locking nuts are suitable for similar applications as the KM series locking nuts, however the addition of the nylon insert located toward the top of the nut deforms over the mating thread, capturing the bolt or stud. This provides a locking feature, causing resistance or prevailing torque, keeping the nut locked in position and resistant to vibration.

In addition to the polyamide insert locking feature, GUK locking nuts have four equally spaced slots machined into the outer diameter of the nut which enable the nut to be secured into position using the appropriate tab washer by bending the tab into the slots.

Note: GUK Nylon Insert Nuts are not suitable in application with high temperatures.
