In our comprehensive guide, we look at the different types of clamps that are available on the market, what the difference is between them, and what you can use them for.
Clamps are hand tools designed to bind or press two or more objects together to keep them firmly in place. This is useful when holding or glueing materials together, for example, wood, paper, plastic, or certain metals.
They generally feature a movable jaw affixed to an adjustable screw, while some designs have two screws. Most types are designed to be used temporarily, however, there are permanent models available. The below diagram shows some of the different parts:
The table below outlines some of the most common types and which applications they’re best suited for.
For safety reasons, it’s important to ensure the correct clamp is being used for the task. Here’s a step-by-step guide on how to use the tool:
Use a piece of scrap wood between the mouth of the clamp and the object, to prevent damage or marking.
Open the mouth using the screw/lever, until it can accommodate the object being worked on.
Turn the screw or release the handle to close the mouth around the object to firmly hold it in place.
Take care that fingers and skin aren’t pinched by the frame or screws.
Don’t overtighten the clamp – if the fit is accurate, only moderate pressure is needed. The tool is designed to maintain a constant pressure between the two surfaces, and not to apply too much force.
