Common Types of Socket and Their Uses

Common Types of Socket and Their Uses

Sockets are a type of hardware used to connect two or more objects together, typically through the use of bolts or screws. They come in various shapes and sizes, and their specific design is dependent on the intended use. In general, sockets are classified into two main categories – impact sockets and standard sockets. However, there are several other types of sockets used for different applications. In this article, we will discuss the common types of sockets and their uses.

1. Standard Sockets
These are the most commonly used sockets and are available in a wide range of sizes, from small ¼ inch to large 2-inch sockets. They are designed to fit onto a ratcheting wrench or a socket handle and are used for general purpose applications. Standard sockets are usually hexagonal in shape, with six sides and a square drive on one end. They are commonly used for tasks such as loosening and tightening nuts and bolts on machinery, vehicles, and household appliances.

2. Impact Sockets
Impact sockets are much more heavy-duty compared to standard sockets. They are specifically designed to withstand the high torque and vibrations produced by impact wrenches. They are made from tougher materials such as chrome-molybdenum steel and have a black finish to differentiate them from standard sockets. Impact sockets come in various sizes and are best used for heavy-duty applications such as automotive repairs and construction work.

3. Spark Plug Sockets
Spark plug sockets are designed specifically for removing and installing spark plugs in an engine. They have a rubber insert to hold the spark plug securely in place and prevent it from getting damaged. These sockets usually have a long and thin neck to reach deep within the engine and are only available in certain sizes to fit different spark plugs.

4. Torque Sockets
Torque sockets are used for torque-limiting applications. They are designed to prevent over-tightening of bolts by rotating only to a certain point before the torque limit is reached. These sockets are commonly used for automotive and aerospace industries, where precise torque specifications are critical for safety and performance.

5. Universal Joint Sockets
Universal joint sockets, also known as universal sockets, are designed to provide flexibility when working in tight or hard-to-reach spaces. They have a swivel joint in the middle that allows the socket to be rotated up to 90 degrees, giving the user more access to difficult areas. These sockets are commonly used in automotive and plumbing applications.

6. Hex Sockets
Hex sockets, also known as Allen sockets, are specifically designed for use with Allen screws and bolts. These sockets have a hexagonal opening that matches the shape of Allen screws, allowing for a secure and precise grip. They are commonly used in electronic devices and furniture assembly.

7. Multi-Drive Sockets
Multi-drive sockets are versatile sockets that can fit onto different types of ratchets and extension tools. They usually have multiple square drive sizes on each end, allowing for easy conversion between different socket sizes. These sockets are ideal for those who need a variety of socket sizes but do not want to invest in multiple tools.

In conclusion, sockets are essential tools for various mechanical and household tasks. They come in different types and sizes, each suitable for specific applications. It is important to know the different types of sockets and their uses to ensure efficient and safe use for different tasks.


In conclusion, sockets are an essential tool in our everyday lives, from powering our electronic devices to facilitating repairs and DIY projects. There are various types of sockets available, each with its unique features and uses. It is crucial to understand the different types of sockets and their purposes to ensure the appropriate selection and safe usage. From standard sockets and impact sockets to specialized sockets like hex and square drive, there is a socket for every task. By familiarizing ourselves with the 12 types of sockets discussed in this article, we can efficiently work with a variety of fasteners and achieve our desired results. So, next time you reach for a socket, remember to consider its features and uses to make your project a success.
