1.What are the main types of bolts?
A: The main bolts are ordinary bolts, high-strength bolts, anchor bolts and so on. Ordinary bolts are generally used for conventional connections; High-strength bolts are suitable for occasions requiring high connection strength, such as steel structure buildings; Anchor bolts are used to secure equipment or structures to the foundation.

2. how to choose the right bolt?
A: The selection of bolts should consider the force of the connection, the use of the environment, installation space and other factors. If the connection force is large, high-strength bolts can be selected; In a humid, corrosive environment, corrosion-resistant bolts should be selected.

3. what are the precautions when installing bolts?
A: Check whether the thread is intact before installation, and the connection surface should be clean and smooth. Pay attention to the direction of the bolt when installing. Generally, the head of the bolt is on the outside of the connected piece and the nut is on the inside.

4. how to properly tighten the bolt?
A: It should be operated according to the specified torque or tightening force, and a torque wrench can be used. Avoid excessive tightening or loosening. For the connection of multiple bolts, tighten them symmetrically and gradually.

5. Is the tightening sequence of bolts important?
A: Very important. Incorrect tightening sequence will lead to uneven force, deformation and other problems, affecting the reliability of the connection. Generally, it is tightened symmetrically from the middle bolt to all sides.

6.why do bolts need to be loosened?
A: When the device is running, the bolted connection may become loose due to vibration and impact, which may reduce the connection strength and reliability, and even cause safety accidents.

7.what are the common bolt loosening methods?
A: Common methods are the use of spring washers, the use of double nuts, the use of stop gaskets and so on. Spring washers use elasticity to produce friction to prevent loosening; Double nuts increase friction by squeezing each other; The stop washer prevents the nut from rotating.
