GUP Nylon Insert Locking Nuts are suitable for similar applications as the ‘KM Series’ locknut.
The addition of the nylon insert, located towards the top of the nut, deforms over the mating thread and captures the bolt or stud. This provides a locking feature, causing resistance – or prevailing torque – keeping the nut locked into position and resistant to vibration.
In addition to the polyamide insert locking feature, GUP 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.
These locknuts are not suitable in applications with high temperatures.
