I have to agree with Tim, After removing thousands of screws over the years in my trucks that I have had or do have and many years of collecting parts in old salvage yards, the clutch head screws are a bit easier to get a bite on then the phillps and by far better then the flat / straight blade screws. I will say I often have a collection of clutch drivers or bits that I tool on some to get a good fit. Best way I find to get a stubborn screw out in sheet metal (no matter its style) is to give it a good tap with a punch n hammer I even hit em fast at home with a point and my air hammer.
