Do the following to prevent bolts from loosening due to vibration:
- Locking Mechanisms: Apply lock nuts, lock washers, or nylon insert nuts to generate friction and hinder loosening.
- Thread Lockers: To produce a firm connection, put liquid thread lockers (such as Loctite) on the threads prior to fitting them together.
- Double Nutting: Use two nuts tightened against each other to create a locking effect.
- Spring Washers: Use spring washers or split lock washers to maintain tension and avoid loosening.
- Correct Torque: Confirm bolts are fixed to the appropriate torque value to prevent insufficient or excessive tightening.
