try a torx bit

if you can get at with a decent pair of pliers, mull-grips try that, thats what i wlways do if summit is rounded off

As Gaz says, a torx is usually a good bet, you can hammer them in if need be and the shape will allow it to cut it's way in giving a tight fit. They also round less easily as the pressure is distributed differently.

centre punch and a hammer, one tap to leave a mark and tap round until loose

I recently had same problem with a rounded off allen key bolt...

For me I used the supplied allen key and a hammer as they seem quite soft, this instantly allowed me to turn the bolt out far enough to get a pair of mole grips on it and wind it out..

Otherwise my next option was a very narrow cold chisel (8mm) and make a slot across the head of the bolt then insert a decent screwdriver or ratchet and wind the bolt out.

Hope this helps
