Trapdoor Pot - what size nuts to secure the hangers?

[JB]

A friend is thinking of a trip down Trapdoor Pot on Dowlass Moss very soon. Does anyone know what size nuts you need to secure the hangers? M???? Not for the Faint Hearted doesn't say.

He's aware that it's worth taking some wires to rig from if any jammed nuts are encountered.

Ta,

Cant give you the answer you require  :-[ - but it reminds of an Andy Kirkpatrick tale from yosemite - he was unsure whether the belay bolts where 8, 10 or 12 mm  on the route, so being a boy scout - he took all three.

When he got there - being in the US - they were of course imperial, not metric. The only thing he could do was use the lagest size metric and wrap a piece of gaffa tape round the treads.  Just to compound the problem - the bolts were placed so that they stuck out slightly 'uphill'. Great if you haning your portaledge etc off em. Not so good if your roped soloing, and if you fall - the belay takes an upward shock load. 
Nice.

NFTFH says:

"many of the pitches are currently rigged on 8mm exploration bolts"

and the rigging section says you'll need 11, plus spares for throwing down the pitch by accident!

Nice one! I'll pass that on.

A few spits have been placed recently, so half a dozen M8 bolts and hangers may come in handy. 'They Think it's All Over' pitch is also well worth a look if you fancy a bit of extra excitement once you've been down Megatron.
