What's The Difference Between 1/2 Inch Pneumatic Tools's Impact Sockets And Regular Sockets?

Many people ask this question. Apart from the difference in color, the next question we usually hear is, “what can these do that regular sockets can’t.

1. Color

Impact sockets are typically black. This is because the surface is carbonized in order for it to harden. Ensuring that the surface is hard allows the sockets to absorb sudden torque changes i.e. “impact” a lot better. The difference in color also helps you to quickly distinguish impact sockets from standard sockets in a toolbox.

2. Metal

Regular sockets are typically made of chrome vanadium whereas a good impact socket is made from chrome molybdenum. Chrome-molybdenum is a ductile metal that is durable and can withstand vibrations.

3. Uses

Standard sockets are typically used with 1/4 inch, 3/8 inch or 3/4 inch ratchets to remove bolts that are not tightly fastened in place.

However, impact sockets are nearly exclusively used with powered impact wrenches or drivers where greater force can be applied and are usually used by mechanics to remove seized nuts and bolts from vehicles. Impact sockets are designed to cope with the vibration caused by an impact wrench.
