***About Internal Hex Drives***
Internal hex drives, also known as hex-socket drives, are similar to hex drives, but have a hexagonal hole in the center that requires an Allen key, also known as a hex key or Allen wrench.
***About Flat head***
Flat head screws are designed to fit flush to the surface when used with countersunk holes.
