Fastener failure analysis
Webto bolt threads and the effect is shown in the diagram. 6. Fatigue cracks usually initiate in the thread roots but can also initiate under the bolt head. Often failure in this location is the result of an inadequate under head radius (resulting in a high stress concentration) or the bolt being mounted on an inclined surface. WebThis is followed by sections providing information on fastener quality and counterfeit fasteners, as well as fastener loads. Then, the article discusses common causes of fastener failures, namely environmental effects, manufacturing discrepancies, improper use, or incorrect installation. Next, it describes fastener failure origins and fretting.
