To avoid loosening or loosening of bolts and nuts, the following methods can be taken: Proper pre-tightening force: When tightening bolts and nuts, appropriate pre-tightening force needs to be applied. The preload force can hold the connectors tightly together and provide enough friction resistance to resist loosening. The correct preload can be determined by using a suitable torque wrench or performing engineering calculations. Use spacers or locking spacers: Placing spacers between the connectors provides additional friction and fastening force. Selecting the appropriate gasket material and thickness can increase the stability of the connection. Anti-loosening gaskets (such as spring gaskets, locking gaskets, etc.) can provide durability of pre-loading force and avoid loosening. Use thread locking agent: Thread locking agent is a chemical applied to the thread that increases the friction between the bolt and nut and prevents loosening. There are two types of thread locking agents to choose from: permanent locking agents and removable locking agents. Choose the right type as needed. Regular inspection and maintenance: Check the tightness of the fittings regularly to ensure that they are not loose or loose. Especially in the connection exposed to vibration, shock or high temperature environment, more attention should be paid to its fastening state. Select the appropriate bolt and nut material: Different materials have different properties, including friction coefficient and loosening characteristics. In special applications, the selection of materials with good heat, vibration and corrosion resistance can effectively reduce the risk of loosening. Please note that the use of these methods depends on the specific application and requirements. In actual operation, measures should be taken to prevent loosening or loosening of bolts and nuts according to the specific use environment and needs.
