Things to Consider Before Buying Corner Clamps

Before you start analyzing all the clamps available in the market or even the ones mentioned in our article, think of the actual reason why you need it.

After you decide on the actual purpose of why you need a clamp, you need to know what features to look for in any clamps. And we are here to help you with that! Let’s cut right to the chase-

1. Jaws

When making the selection of the correct clamp for your work, jaws are the ones you should check first. Because only jaws will come in contact with the item, you will be working with. The clamp passes all the pressure on to its jaws to hold the pieces tightly. And the pressure is exerted on a tiny area of the surface.

So, if the jaw is not constructed in a good way, they may mar all your items. You should purchase the ones with larger jaw faces; this won’t let them cause indentations because larger faces will help to spread the pressure all over the surface.

2. Mechanism

The mechanism of the clamp itself has a big impact on its overall performance. If the arrangement is excellent, it will be able to exert more pressure than normal ones.

Clamps that have threaded bars take time to deploy but will allow them to screw it very tightly and exert much pressure on the items. So, instead of buying the clamps with quick action, consider buying the one with threaded bars.

3. Throat depth

You may deal with pieces of different shapes and sizes. If the throat depth of the clamp is deep enough, you won’t face any problems with your projects. Because the throat depth determines how deep it reaches. There are lots of available clamps with V groove. Those are the best options for you based on throat depth.

4. Clamping pressure

Clamps of different types and designs can exert the pressure of different amounts. You shouldn’t buy a clamp capable of exerting too much pressure for your delicate items; it can damage your items or even break them.

If you are going to work with larger items, you need to buy the one that can exert much pressure. Or else, the clamp won’t be able to keep the pieces in place.

After analyzing the clamps based on these mentioned features, we are sure that you will be able to buy the perfect clamp for your project.
