Impact VS. Regular Sockets: What Is The Difference?
When considering shocks vs. regular sockets, you may wonder why there is a price difference between the two. After all, aren’t they doing the same job? The answer to that question is, of course, "yes" - but the way they complete the task explains not only the extra cash associated with the impact units, but also their different structures.
WHAT IS AN IMPACT TOOL?
A quick primer on how impact tools work. Instead of using human power to turn the sleeve, they turned it by hitting an anvil with a set of small hammers - hence the word "impact". The hammer itself is powered by air or electricity and strikes the anvil at high speed, providing a significant mechanical advantage when trying to turn a bolt.
Then consider that the impact has to withstand a different level of force when in use than a regular socket. The repeated impacts of the hammer, coupled with the torque exerted on the socket, require a different approach to constructing the tool itself.
VERY METAL
Some of the key differences between impact sockets and regular sockets are directly related to the need for extra strength in the former. The first and most important is the metal used. Unlike the chrome vanadium finish found on most handheld sockets, the shock units are made from chrome molybdenum and then carbonized, giving it a solid black appearance.
Molybdenum, as a metal, absorbs vibration better than vanadium, which tends to crack and splinter when repeatedly struck by the hammer of an impact driver. Carbonized metal also helps increase the overall strength of the metal itself.
You'll also find a locking pin inside most impact sockets to prevent them from vibrating away from the tool while in use.
CHOOSE WISELY
Can impact sockets be used with hand tools? Of course, though you'll notice they're heavier than standard sockets, and the borders may be too thick to fit in tighter spots. Can the impact gun use a regular socket? Yes, but you run the risk of shortening the socket's life due to vibration and stress associated with the drive.
Choose the right tool for the job every time and you'll have far fewer problems working on your projects.
