The reasons for the loosening of bolts and nuts are usually the following: Load vibration and vibration: If the parts connected to the bolts are subjected to continuous or intermittent vibration or vibration, the bolts and nuts will gradually loosen. Improper preload: When tightening bolts and nuts, if enough preload is not applied correctly, the bolts and nuts will gradually loosen during use. Use of inappropriate thread locking agent: If the appropriate thread locking agent is not used, the bolt and nut may not remain tight. To solve the problem of loose bolts and nuts, consider the following methods: Tighten bolts and nuts: Ensure that they are tightened with the correct torque value during installation, and use tools such as torque wrenches to achieve the required pre-tightening force. Use thread locking agent: Select the appropriate thread locking agent to prevent bolts and nuts from loosening. Thread locking agents are generally divided into permanent locking agents and detachable locking agents, which can be selected according to actual needs. Regular inspection and maintenance: Check bolt fastening status regularly and re-tighten when necessary. In addition, in high vibration environments, you can consider adding a locking gasket or using a liquid gasket to improve bolt fastening performance. The above methods are intended to help solve the problem of bolt and nut loosening, but specific measures should be selected and implemented according to the actual situation. To ensure safety and reliability, consult relevant professionals when necessary.
