The advantages of anti loosening washers

1. Ensure that the clamping force of the connector is still maintained under strong vibration, better than fasteners that rely on friction to lock;

2. Prevent bolt loosening caused by vibration and prevent related problems caused by loose fasteners from occurring again;

3. No special installation work is required, making it easy to install and disassemble;

4. Changes in temperature will not loosen the connectors;

5. It has durability;

6. Reusable.

The anti loosening washer has the characteristic of simple installation.

1. Simply place the inclined tooth surfaces on the inner side of the two gaskets opposite each other and between the nut and the connecting material;

2. After tightening the nut, the radial convex surface on the outer side of the anti loosening washer is in an interlocking state with the contact surfaces at both ends, and the slope angle of the inclined tooth surface on the inner side of the washer is greater than the thread angle of the bolt;

When the bolt is stretched due to mechanical vibration, the nut will rotate and loosen accordingly. Due to the radial grooves on the outer side of the anti loosening washer, the frictional force is greater than the frictional force between the inclined tooth surfaces on the inner side. In this state, only relative displacement between the inner inclined tooth surfaces is allowed, resulting in a certain amount of lifting tension;

When the bolt contracts, the helical tooth surface of the washer will cause the nut to return to its original position. Thus achieving 100% anti loosening and tightening effect;

5. Washers are suitable for relatively flat and smooth surfaces;

If the connecting material is non-metallic, a metal plate can be fixed on the connecting material, so that a locking washer can be used;

7. There is no need to use a torque wrench when installing the lock washer;

8. Pneumatic tools can be used when installing or removing lock washers.

Anti loosening washers are suitable for equipment that frequently vibrates and can be applied in industries such as:

Automobile industry – sedans, trucks, buses

compressor

construction machinery

Wind power generation equipment

Agricultural machinery

Foundry industry

Drilling equipment

Shipbuilding Industry

military

Mining equipment

Oil drilling rig (onshore or offshore)

Public facilities

rail transit

drive system

Metallurgical equipment

Rock hammer
