Anti-loose method:
*Mechanical anti-loose
*Riveting and anti-loose
*Anti-loose friction
*Structure anti-loose
*Flushing method to prevent loosening
The installation method of the anti-loosening nut mainly includes the following steps and precautions:
1. Preparation before installation:
Prepare necessary tools such as wrenches and torque wrenches.
Clean threaded holes and bolts, remove debris and dirt, and ensure that the threads are clean and unobstructed.
Anti-seize agent or lubricant can be applied to the threads to reduce obstruction during tightening.
2.Steps during installation:
First, put the washer on the bolt to ensure that the washer fits tightly with the nut without any gap.
Use a torque wrench to gradually tighten the nut according to the specified torque value, ensuring that the force is moderate and avoid being too tight or too loose.
For multiple bolts, tighten them gradually in an alternating diagonal manner to ensure uniform force.
3.Inspection and maintenance after installation:
Check the condition of nuts and washers regularly, and replace severely worn parts in time to ensure long-lasting anti-loosening effect.
Apply anti-rust oil to reduce corrosion and extend service life.
