Product Feature of Fulcrum Pins
Features of Fulcrum Pins
In some important occasions we will take some anti-loosening measures to ensure the reliability of nut locking. Fulcrum Pins, Lock Nut is one of the anti-loosening measures.
The anti-loosening effect of the lock nut mainly depends on the interaction force between the meshing threads of the nut and the bolt. There are many ways to improve the interaction force between the meshing threads such as the structural improvement of the nut thread, Nylon roughening of Nylon nut, and thread surface treatment.
Thin, suitable for installation environment where thickness space is limited

Frequently asked question (FAQ)
- Question: Does the lock nut need to be greased?
- Answer: Lubricant is required for both tightening and loosening. If the hardness of the fixed shaft is relatively low, please use a grease with high lubricity.
- Question: Precautions when fixing
- Answer: In order to ensure the maximum effect of the lock nut, please expose at least 2 inches of the threaded part when fixing. Standard type lock nut is a round nut, with four small slots around its outer perimeter, which can be tightened on the stud body using a crescent wrench. The lock nut should be equipped with a shaft washer, which allows the small slot on the stud body to be fixed relative to its peripheral small slot, preventing its loosening.
- Question: Differences between a standard nut and a lock nut (1)
-
Answer:
1. Vibration resistance is not the same
Standard nut: inferior relative to the lock nut
Lock nut: superior anti-vibration performance. When the thread is tightened, the top of thread of the bolt closely enters the 30° wedge-shaped slope of the nut to be clamped, and the normal force exerted on the wedge-shaped slope forms an angle of 60° with the axis of the bolt instead of The included angle of 30°. Therefore, the normal force generated when the locknut is tightened is much greater than that of the standard nut, and it has a great anti-loosening and anti-vibration ability. - Question: Differences between a standard nut and a lock nut (2)
-
Answer:
2. Wear resistance and shear resistance are not the same
Standard nut: poor abrasion resistance and shear resistance;
Lock nut: excellent wear resistance and shear resistance. The 30° inclined surface of thread bottom of the nut can make the nut locking force evenly distributed on all the threads of each ridge. Since the compression force on the thread surface of each ridge is evenly distributed, the nut can better solve the thread wear and shear deformation problem. - Question: Differences between a standard nut and a lock nut (3)
-
Answer:
3. The reutilization rate is not the same
Standard nut: low reutilization rate;
Lock nut: high reutilization rate. Extensive use shows that after repeated tightening and disassembly of the anti-loosening nut, its locking force is still not reduced, and the original locking can be maintained.
