A socket in mechanical engineering refers to a closed-end fitting designed to receive and engage with the head of a fastener, such as a nut or bolt. Sockets are typically used in conjunction with a wrench or other driving tool to tighten or loosen fasteners.
Key Facts
- Socket wrench: A socket wrench, also known as a socket spanner, is a type of spanner or wrench that uses a closed socket format to turn a fastener, such as a nut or bolt.
- Interchangeable sockets: Sockets come in various sizes and types to fit different fasteners. The advantage of interchangeable sockets is that instead of having a separate wrench for each fastener size, only separate sockets are needed.
- Square drive: Sockets are attached to the driving tool using a male/female square connection fitting called the square drive. Standard sizes of square drives include 1/4, 3/8, 1/2, 5/8, 3/4, 1, 1+1/2, 2+1/2, and 3+1/2 inches.
- Ratcheting mechanism: The most prevalent form of socket wrench is the ratcheting socket wrench, often called a ratchet. It incorporates a reversible ratcheting mechanism that allows the user to pivot the tool back and forth to turn the socket without removing and repositioning the wrench.
- Other driving methods: Besides ratcheting socket wrenches, there are other methods of driving sockets, including pneumatic impact wrenches, hydraulic torque wrenches, torque multipliers, and breaker bars.
Interchangeable Sockets
One of the key advantages of sockets is their interchangeability. Instead of having a separate wrench for each size and type of fastener, sockets allow for the use of a single driving tool with multiple interchangeable sockets. This versatility makes sockets a highly practical and efficient tool for a wide range of mechanical applications.
Square Drive
Sockets are typically attached to the driving tool via a square drive connection. The square drive provides a secure and stable interface between the socket and the wrench. Standard square drive sizes include 1/4, 3/8, 1/2, 5/8, 3/4, 1, 1+1/2, 2+1/2, and 3+1/2 inches.
Ratcheting Mechanism
The most common type of socket wrench is the ratcheting socket wrench, often referred to as a ratchet. Ratchets incorporate a reversible ratcheting mechanism that allows the user to pivot the tool back and forth to turn the socket without removing and repositioning the wrench. This mechanism significantly increases efficiency and speed, especially in applications where repeated tightening or loosening of fasteners is required.
Other Driving Methods
In addition to ratcheting socket wrenches, there are other methods of driving sockets. These include:
- Pneumatic impact wrenchesPowered by compressed air, impact wrenches deliver high-torque impacts to quickly tighten or loosen fasteners.
- Hydraulic torque wrenchesProvide precise torque control for critical applications where accurate tightening is essential.
- Torque multipliersMultiply the torque applied by the user, enabling the tightening or loosening of extremely tight fasteners.
- Breaker barsLong, sturdy bars used to break loose seized or rusted fasteners.

A ratcheting socket wrench, commonly known as a ratchet, incorporates a reversible ratcheting mechanism that allows the user to pivot the tool back and forth to turn the socket without removing and repositioning the wrench.
What are some other methods of driving sockets?
Besides ratcheting socket wrenches, other methods of driving sockets include pneumatic impact wrenches, hydraulic torque wrenches, torque multipliers, and breaker bars.
What are the different types of sockets?
Sockets come in various shapes and sizes to fit different types of fasteners. Common socket types include hexagonal, 12-point, Torx, and spline sockets.
What are impact sockets?
Impact sockets are designed to withstand the high-torque impacts delivered by impact wrenches. They are typically made from a thicker, tougher alloy steel than standard sockets.
What are the different sizes of square drives?
Standard square drive sizes include 1/4, 3/8, 1/2, 5/8, 3/4, 1, 1+1/2, 2+1/2, and 3+1/2 inches.
