Advanced Locknut Solutions for Vibration Resistance #
When it comes to securing bearings and components in demanding industrial environments, the right locknut can make all the difference. This page introduces two specialized locknut solutions that eliminate the need for washers while providing reliable resistance to loosening from vibration and torque.
Prevailing Torque Bearing Nut with Metal Insert #
A prevailing torque bearing nut with a metal insert is engineered to prevent self-loosening. The key feature is the prevailing torque, achieved by distorting the threads at the top of the nut. This design ensures a secure fit and reliable locking action, even under challenging conditions.
There are three main mechanisms by which prevailing torque locknuts operate:
- Localized Plastic Deformation: Some of the initial threads on the nut are plastically deformed, creating multiple points of interference with the mating part. This ensures a tight fit as the nut is installed.
- Interference Fit: The threads of the locknut have negative clearance, meaning there is no initial contact or deflection with the mating part until torque is applied.
- Continuous Sliding: As the nut is tightened, the thread surfaces of the locknut and bolt slide against each other, maintaining contact and friction.
These all-metal locknuts are particularly valued in applications involving high temperatures, high torque, significant vibration, corrosion, and high tensile strength. Their robust design makes them a preferred choice across various industries.

GUK Self-Locking Nuts #
GUK self-locking nuts are designed to resist loosening caused by vibration and torque. These nuts, including elastic stop nuts and prevailing torque nuts, utilize elastic deformation in their uppermost threads to create a locking action. This frictional interference between the nut and the mating component ensures a secure connection.
Key advantages include:
- Vibration Resistance: The unique thread shape and self-contained locking feature prevent loosening, even under heavy vibration.
- Reusability: Safety lock nuts can be reused a limited number of times, though the prevailing torque decreases with each use.
- Simplified Assembly: By eliminating the need for additional security elements like washers, these nuts streamline assembly and reduce component count.
- Cost-Effectiveness: A single locknut can secure multiple objects, offering a practical solution for vibration-prone environments.
- Thread size: M100.75 to M1002.0

Why Choose These Locknuts? #
Both the prevailing torque bearing nut with metal insert and the GUK self-locking nut offer robust solutions for applications where vibration, shock, and high torque are concerns. Their innovative designs reduce the need for additional components, simplify installation, and provide reliable performance in demanding environments.
