Just to let you know that another bolt has failed at Kleinmond. Allan Hills took a whipper on Perculator which resulted in the crux bolt breaking.
I have looked at the bolt and it is very clearly Stress Corrosion Cracking (SCC) that caused the failure.
Very little of the cross sectional area was left as a result of the SCC. Please treat all express anchors at coastal crags and Oudtshoorn with caution.
