Mechanics use a variety of sockets for their work, depending on the task at hand. The most common type is a 12-point socket, which has twelve points around its circumference that are designed to fit nuts and bolts with an equal number of sides. Another popular choice is the 6-point socket, which features six flat sides that provide better grip when removing or tightening fasteners with fewer than 12 sides. Hex sockets are also used frequently in automotive repair due to their hexagonal shape, allowing them to fit perfectly over hex head bolts and screws. Finally, deep well sockets can be extremely useful as they allow access to hard-to-reach fasteners found in tight spaces such as engine bays or wheel wells.
