Impact wrench sockets and regular sockets are designed for different purposes. Regular sockets are typically used with hand tools and are made of chrome vanadium. On the other hand, impact wrench sockets are used with powered impact wrenches or drivers, and are made of chrome molybdenum. The chrome molybdenum used in impact wrench sockets is more ductile and durable, allowing it to withstand vibrations and absorb torque changes better than regular sockets. Impact wrench sockets also feature a locking pin to prevent them from vibrating off the tool during use. While regular sockets are suitable for light-duty, manual work, impact wrench sockets are designed for heavy-duty impact work and can also be used for light-duty tasks.
Characteristics | Values |
---|---|
Wall thickness | Impact sockets have walls that are around 50% thicker than regular sockets. |
Colour | Impact sockets are typically black, whereas regular sockets are chrome-coloured. |
Use | Impact sockets are used for heavy-duty impact work, but can also be used for light-duty work. Regular sockets are used for manual light-duty work. |
Material | Impact sockets are made from chrome molybdenum steel, whereas regular sockets are made from chrome vanadium steel. |
Durability | Impact sockets are more durable and have stronger rust resistance and life span. |
Safety | Regular sockets are likely to shatter when used with power tools, which can be dangerous. |
Locking pin mechanism | Impact sockets have a hole for a retaining/locking pin to attach to the impact wrench anvil. There are two types of locking pin mechanisms: detent pin and O-ring and pin. |
What You'll Learn
Impact sockets are made from chrome molybdenum
Chrome molybdenum is more ductile than chrome vanadium, meaning it can withstand the repeated hammering of an impact tool without cracking. This is because the addition of molybdenum to the alloy increases its flexibility, allowing it to better absorb shock. This makes chrome molybdenum a safer option for impact sockets, as it significantly reduces the chance of the socket shattering when used with an impact driver.
The use of chrome molybdenum for impact sockets is particularly important when considering safety. The toughness and flexibility of chrome molybdenum help to maximise safety and reduce the risk of injury. This is in contrast to chrome vanadium, which has a higher risk of shattering when used in high-impact applications.
The colour of impact sockets made from chrome molybdenum also helps to distinguish them from regular sockets. Chrome molybdenum products are typically a dark matte grey colour, whereas chrome vanadium sockets are usually chrome-plated and shiny. This visual difference makes it easier for users to select the appropriate socket for the task at hand.
In summary, impact sockets made from chrome molybdenum offer superior performance, durability, and safety compared to other materials. The ductility and toughness of chrome molybdenum make it the ideal choice for impact sockets, ensuring that they can withstand the demands of high-impact applications without cracking or shattering.

Regular sockets are used for light-duty work
Regular sockets are used for light-duty, manual work. They are commonly chrome in colour, indicating that they have a chrome plating. This plating is likely to chip off if used for intense, heavy-duty work. Regular sockets are usually made from chrome vanadium steel, which is structurally strong but more brittle than impact sockets, making it prone to breaking when exposed to shock and vibration.
Regular sockets are designed for use with hand tools, such as handheld ratchets, T-handles, and screwdrivers. They are not suitable for use with power tools, as their thinner walls are likely to crack or shatter when paired with high-power tools.
Regular sockets are also distinguished by their glossy finish, as opposed to the matte finish of impact sockets. They do not have a hole at the attachment end, unlike impact sockets, which feature a hole for a retaining or locking pin to attach the socket and driver firmly.
Regular sockets are generally more affordable and are suitable for light-duty, non-impact work. They are ideal for daily personal use, such as manual ratcheting, and are commonly found in basic tool kits.

Impact sockets are black due to carbonization
The black oxide coating also offers functional benefits for impact sockets. Its rough texture enhances grip, making it easier for users to handle the sockets with greasy hands. Additionally, the black colour provides a visual distinction from regular chrome sockets, allowing for easier identification and differentiation between the two types.
It is worth noting that not all impact sockets are black. Some manufacturers produce impact sockets with a chrome finish using a process called "Flexzychrome," which is designed to prevent chipping and cracking. However, black oxide coatings remain prevalent due to their effectiveness in preventing rust and providing a safe, durable finish for impact sockets.
The choice of finish for impact sockets is influenced by the intended use and the desired level of durability and safety. The black oxide coating may be more prone to rusting than chrome finishes, but regular use can mitigate this issue. Ultimately, impact sockets prioritize function and safety over aesthetics, and the black oxide finish is a testament to that design philosophy.

Regular sockets are chrome-coloured
Chrome vanadium is also known as chromoly, which is made from chromium, molybdenum, iron, and carbon alloy elements. Chrome vanadium sockets are also commonly colour-coded. While the most common colour for chrome vanadium sockets is a silver or mirror-like finish, they can also be found in colours such as blue, green, purple, red, and yellow.
Chrome vanadium sockets are mostly used for manual, light-duty work. They are unfit for impact usage due to their hardness, which makes them susceptible to cracking when used with high-power tools.
Impact sockets, on the other hand, are produced from chrome molybdenum, which is tougher than chrome vanadium and can withstand the repeated hammering of an impact tool without cracking. Impact sockets are mostly black in colour and are used for heavy-duty impact work, as well as light-duty work.

Impact sockets are used with powered impact wrenches
Impact sockets are constructed from chrome molybdenum steel, which is ductile and durable. This ductility means that the socket can withstand the repeated hammering of an impact tool without cracking. The metal is also able to absorb vibrations better than chrome vanadium steel, which is used for regular sockets.
The wall of an impact socket is around 50% thicker than that of a regular socket, making it suitable for use with power tools. The thicker walls and ductile metal of the impact socket mean that it is less likely to shatter or crack under high force. This is in contrast to regular sockets, which are prone to breaking when exposed to shock and vibration.
The use of a locking pin inside impact sockets is another important feature when used with powered impact wrenches. The locking pin keeps the socket firmly attached to the impact wrench anvil, preventing it from vibrating off during operation. This ensures safety in the workspace and helps to prolong the life of the socket and tool.
Impact sockets are typically black in colour due to the carbonization process, which hardens the surface and improves its ability to absorb torque changes. This colour difference also allows for easy distinction between impact and regular sockets.

Frequently asked questions
Impact sockets are typically black and made from chrome molybdenum, a ductile metal that is durable and can withstand vibrations. Regular sockets are typically chrome in colour and made from chrome vanadium, which is structurally strong but more brittle. Impact sockets are used with powered impact wrenches or drivers where greater force is needed, whereas regular sockets are used with hand tools.
Impact sockets are more expensive than regular sockets because they are professional-grade and used for heavy-duty impact work. Regular sockets are average in quality and used for light-duty, non-impact work.
Yes, you can use impact sockets with hand tools. However, they are heavier than standard sockets and may be too thick to fit into tight spots.
