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.
(Alan was the 3rd person to try Percolator (30) that day and after he took two foot fall, the crux bolt failed- Scary stuff! Well done Llewelyn (who suffered a bad rope burn) on catching this unexpected fall).
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.
