Saddle clamp bolt problem

Just got a 2013 Giant Defy Composite 3 and need to adjust the saddle. Problem is I'm having trouble with the allen bolt fixing the saddle to the seatpost - I initially tried a 5mm allen key but this slipped and burred the bolt to some extent. 6mm key is too big.

Is it possible this bolt is 5.5mm (I don't have one to try at present) - it still looks useable if so?

Or - do I need to resort to other methods/return to the shop to undo and replace the bolt?

The bolt is marked "T" inside. Both saddle and post are Giant's own (Defy saddle, Defy Vector Composite post). Cheers.

    It will be 5mm - 5.5mm Allen key doesn't exist. If you can't get it to grip, try using a Torqx bit as it has splines that will bite. Next, try glueing a 5mm Allen key in place. Finally, you may be able to cut a slot for a screwdriver using a hacksaw or Dremal.

    Strange that I've got some in my tool sets.

    5.5 mm Allen keys do exist. I have one.
