Prevailing torque bearing nut with metal insert: No washer needed

The Prevailing torque bearing nut with metal insert is a type of lock nut that features a prevailing torque to assist in preventing self-loosening. The metal prevailing torque locknuts get the feature of prevailing torque when the threads are distorted at the top of the nut.

When high temperatures, high torque, high vibration, corrosion, and tensile strength are involved in any process, industries rely on all metal prevailing torque nuts.

GUK Self-Locking Nuts: No washer needed

Guk self-locking nut is a nut that resists loosening under vibrations and torque. Elastic stop nuts and prevailing torque nuts are of the particular type where some portions of the nut deform elastically to provide a locking action.

The special shape of the thread of the safety lock nut effectively prevents failure and at the same time reuses the nut. Also, the number of components is reduced by the self-assurance of the base, since no further security elements are needed. The screw lock counteracts the unintentional release, without the need to process the screw itself.
