360 partially rounded head bolt help

Use a six sided socket on all "stuck" nuts and bolts!!!

If even the six sided one won't get it, then weld a large nut onto the bolt head thru the hole in the nut and then use the correct six sided socket to get that.

ok i though 12 points were better because the put more pressure on the sides of the bolt. and i dont have welding equipment so i cant weld on it.
