Socket head screws are also called Cap screws as well. I find that the biggest benefit of using them is for access with tooling. You can get to them without the need for large spaces to fit a spanner and they can be counter sunk into your job as well. Just take care when tightening them up if you are using ball-end keys. I have snapped a few of them off inside the cap screw, particularly with cheaper tooling.
