A few notable historical failures have been traced to pyrotechnic connectors failing to break at the right time. WebClimbing bolt failures can occur due to a variety of reasons. Some common causes of bolt failure in climbing include corrosion, improper installation, and age. Corrosion is a major factor that can contribute to bolt failure. Over time, bolts can corrode due to exposure to moisture and environmental factors.
