I haven't come across any that are small enough normally
often a Torx type bit slightly larger than hex will work
if it's a countersunk head you can often gently drill head off to reveal stud that you can grasp with pliers
sometimes heating an old hes driver in gas ring off cooker than transferring to striped hex for a good few seconds to transfer heat works then use you best driver to try remove
had good success with MIP drivers as they appear to be top notch quality wise
