I'm trying to undo the load lashing bolts, but they seem to be properly stuck. I've tried a starry shaped bit (it has about half of the indentations as the bolt) and an allen key, but I've only managed to remove what was left of one of the bolt heads already. Is there a tool that's specifically designed to do the job? Or any other way of getting them out?
