It's not ideal, but it's unlikely to be too bad yet - there's plenty of meat in that chain yet, and even without the washer it'd have a hard time getting over the bolt. It's worth keeping an eye on, and I'll swap it out if it starts looking too dodgy next time I take a drill that way (don't hold your breath though, I've had vague plans to pull the dodgy bolt on Scones for ages).
Simey - it's on Blackboard Wall at Berowra, so 90 degree cliff top and dead vertical wall. Undercutting isn't an issue, at least on that section of the crag. |
