Which statement is true about socket sizes and their drive end?

• A. Sockets are sized by fractions/millimeters and the drive end size.
• B. Sockets are defined solely by their color.
• C. Sockets are sized only by length.
• D. Sockets do not have drive ends.

Answer: (A)

Socket sizing involves two parts: the bore that fits the fastener (sized in fractions of an inch or millimeters) and the drive end that mates with a ratchet or driver. The correct idea here is that sockets are defined by both the opening size and the drive size. The opening size tells you which fasteners it fits, while the drive end (the square connection) determines which ratchet or driver it attaches to. Colors or length alone don’t define size, and every socket has a drive end to connect to a tool.
