What to look for
Good to know
What is the best metric clamp for heavy duty woodworking?
The Bessey K Body Revo is best for heavy duty tasks due to its high clamping force and parallel clamping capability.
Can I use metric clamps for welding?
Some clamps can handle welding heat, but not all. Look for clamps with steel bodies and heat resistant pads. Bessey K Body is not recommended for welding.
What is the difference between a bar clamp and a pipe clamp?
A bar clamp has a fixed bar, while a pipe clamp uses a pipe as the bar. Pipe clamps can be longer but require a separate pipe.
How do I determine the right clamp size?
Measure the thickness of your workpiece and the distance you need to clamp. Add some extra length. A general rule is to have a clamp that is at least one third longer than the work.
Are more expensive clamps worth the money?
For frequent or professional use, yes. Higher priced clamps often offer better durability, stronger clamping force, and smoother mechanisms. For occasional DIY, cheaper options may suffice.
Can I leave clamps on wood overnight?
Yes, but you should check the pressure. Over tightening can leave marks. Use protective pads to prevent dents.
What does ‘parallel clamping’ mean?
Parallel clamps maintain a parallel orientation between the bar and the workpiece, applying even pressure across the entire surface. This is crucial for glue ups.
How many clamps do I need for a project?
It depends on the size. For a small box, two clamps may be enough. For a table top, you might need four or more. Always have more than you think you need.
Can I use metric clamps with imperial measurements?
Yes, metric clamps can be used with any project. The markings are in metric, but you can measure as needed. The clamp works the same.
Our take
For most users, the Bessey K Body Revo is the best overall clamp. It offers exceptional force and precision. If budget is a concern, the IRWIN Quick-Grip is a solid value. For long reach, choose Pony pipe clamps.
