Could be a factory issue on what they had handy at the time. My truck has very few Phillips head screws, and lots of clutch head screws.
The door striker plate, the window retaining screws, the rear fender bolts. Front fenders have regular bolts holding everything together.
The screws that hold the glove box hing and lid are clutch head.
So it may depend on what the factory had at the time of the build.
Either way, I still enjoy my old truck.
