The Possible Causes Of Bolt Breakage

In the previous article, we shared Some Common Cases Of Bolt Breakage. In this article, as a professional fastener company, we will continue to analyze the possible causes of bolt breakage.

Quality problems with bolts

Many batches of bolts have been replaced on-site, some bolts have been checked, and no problems with bolt quality have been found, so this possible situation can be basically ruled out.

Brittle fracture of bolts

The typical characteristics of hydrogen embrittlement fracture are fibrous fractures, and the fractures are relatively flat, as shown in the figure below. According to the characteristics of bolt fracture observed on site, the broken bolt of the unit does not conform to hydrogen embrittlement fracture.

The typical characteristics of fatigue fracture of bolts are the existence of a belly-shaped fatigue line. The crack source can be found along the reverse direction of the fatigue arc, as shown in the figure below. The broken bolt of the unit in the field conforms to this characteristic.
