Causes of bolt breakage

1. Bolt Material: Using high-quality materials results in better bolt quality. Conversely, using inferior materials increases the likelihood of breakage.

 

2. Insufficient Bolt Strength: If the pressure exerted on a bolt exceeds its strength, it is prone to fracture. Therefore, it's crucial to understand the bolt's strength rating before use to select bolts with higher strength, significantly reducing the likelihood of breakage.

 

3. Manufacturing Defects: Many bolts fail to meet standard quality requirements due to substandard manufacturing processes, leading to breakage. Proper testing after production is essential to ensure bolt quality before sale, providing consumers with a basic guarantee.

 

4. Bolt Fatigue Strength Limits: The most common cause of bolt fracture is insufficient bolt fatigue strength. There are no problems when we first use bolts, but they may loosen after working with the object. If we continue to work with them when they are loose, the fatigue strength of the bolt will increase. When the bolt reaches the limit that it can withstand, it will break.
