About Hex Socket Drives
Hex socket drives, also known as internal hex drives, have a hexagonal hole in the center that requires an Allen key, also known as a hex key or Allen wrench.
About Socket cap screws
Socket cap screws, also known as Allen head screws, have a recessed drive, and are commonly used when there is not enough clearance for a conventional wrench or socket. They are fastened with an Allen wrench, which is also called a hex wrench or hex key.
