What to look for
Good to know
What is the strongest type of wrench?
The strongest type is typically a solid combination wrench made from high grade alloy steel. For breaking bolts, a breaker bar offers the most torque.
Are expensive wrenches worth the cost?
For heavy use, yes. They are made from better materials and last longer. For occasional use, mid range tools may suffice.
Can I use an adjustable wrench for heavy duty work?
Adjustable wrenches are not recommended for high torque because they can slip. Use a fixed wrench for maximum torque.
What is the difference between chrome vanadium and chrome molybdenum?
Both are strong alloys. Chrome molybdenum is often used for impact sockets because it is tougher. Chrome vanadium is common for hand tools.
How do I choose the right size wrench?
Measure the fastener size. For sets, choose a range that covers common sizes in your work. Metric and standard are different, so buy accordingly.
Do ratcheting wrenches save time?
Yes, they allow you to tighten or loosen without removing the wrench each time. This speeds up tasks with multiple fasteners.
Can I use a wrench with a cheater pipe for more torque?
We advise against it. It can damage the wrench and cause injury. Use a longer wrench or a breaker bar instead.
How should I store my wrenches?
Store them in a dry place to prevent rust. A tool chest or wall mount keeps them organized and protected.
The verdict
For most users, the GEARWRENCH 72 Tooth Flex Head is the best choice. It offers a good balance of strength, flexibility, and convenience. If you need maximum torque for rusted bolts, the TEKTON Breaker Bar is a solid investment. For professional use, the Proto J12000 is worth the cost. Choose based on your specific needs, but any of these will serve you well.
