Many death trap bolts in Sardinia and other marine crags

Gianluca Piras has published a horror video from a 6b+ in Masua, Lovely Licia. The glue-in bolt was just some ten years old but it breaks in his hands after seconds. Maurizio Oviglia, a Sardinia local, says that the first breakage on the island happened in 2012 and later at least another 20 stainless steel 304 bolts have got broken. The terryfying fact is that bolts which appear to be in quite good shape can break as well due to SCC internal stress corrosion cracks, mainly in marine environment. We have asked the bolt manufacturer Raumer to comment and we will follow up. Here is the UIAA report from 2015, warning against stress corrossion. Oviglia would like to spread the info that bolts are at risk, especially in Biddiriscottai, Casarotto, Millennium and Cala Fuili/Cala Lina. It should also be mentioned that the glue-in bolt should have been placed much deeper so that the ring would have contact with the rock.
