Bolts mainly play a role in connecting mechanical equipment. The quality of bolts will directly affect the performance of mechanical equipment. The common failure of bolts is a fracture. Then the 2H Heavy Hex Nuts manufacturer will introduce how to prevent bolt fracture. Methods:


1. When running 12000km for secondary maintenance, the engine oil pan should be disassembled to check the use of the engine bearing bush. If the clearance of the individual bearing bush is found to be too large, it should be replaced, and the connecting rod bolt should be replaced at the same time. If you find that the engine is running unsteadily or abnormal noise during normal operation, you should stop and check-in time.


2. Check the newly replaced connecting rod bolts during each maintenance. Pay attention to whether there are cracks or dents on the head, guide part, and thread parts of the bolt, and whether the tooth shape and thread pitch of the thread are abnormal.


3. When assembling the connecting rod cover, use a torque wrench to tighten it according to the specified standard to prevent excessive or small torque.


4. Use connecting rod bolts produced by supporting factories.
