Have you ever noticed an engraving on one of your tools that reads “CR-V” or “CRV?” Have you ever wondered what that stands for – or what it really means?
In this blog post, you’ll discover the meaning of the abbreviation “CR-V” in the context of tools.
What Does “CRV” Mean on Tools?
“CR-V” stands for “Chromium-Vanadium” – a type of steel known for its strength and durability.
These characteristics make it ideal for making tools, such as:
- Socket wrenches
How strong is chromium-vanadium steel?
On the Rockwell Hardness Scale, chromium-vanadium steel has a rating of C41-55.
If you’re unfamiliar with the Rockwell Hardness Scale, the “C” indicates hard steel (chromium, in this case).
Are CRV Tools Good?
In short, yes – tools made from chromium-vanadium are excellent.
Not only are they durable, but they also withstand rust better.
In the case of sockets, a CR-V socket also fits easier in places where a thicker impact socket won’t go.
However, it’s crucial to remember that CR-V sockets are primarily designed for hand tools. In other words, don’t attempt to use a CR-V socket with any impact tools like an impact wrench.
If you, despite this, use a CR-V socket with an impact gun, there’s a great risk that you’ll brake either the bolt or screw you’re trying to loosen or tighten. It’s even possible that you’ll brake the socket itself.
Therefore, stick to using impact sockets for impact tools and CR-V sockets for manual hand tools.
