This time we will talk about a tool that is indispensable for those who are builders or furniture makers, whether they are professionals or beginners. We are referring to the clamps, it is a tool that helps us to join two objects together during a construction.

Clamps are equipment that allow us to hold firmly two objects that we want to join in a permanent way either with some glue or welding point. They are useful for holding or gluing materials such as wood, paper, plastic or some metals; and they come in various sizes and shapes depending on the materials to be joined.

At ReviewBox we want to help you find the best clamp that will allow you to finish your work quickly and comfortably. That’s why we’ll show you the various shapes and materials they can be made of, along with the main features and benefits of a safe and effective construction.


  • Clamps are construction equipment that allow us to join two materials together in a rigid and stable way while applying a binder or a welding point to fix them in that position permanently. There are clamps for different materials, as well as different shapes and sizes depending on the work to be done.
  • There are a large number of clamps available on the market. These can be classified in up to 38 models, but there are 8 that are the most used for wood and metal work.
  • Knowing the material to be worked on together with its dimensions and the safety factor of the clamps are essential elements to make a proper purchase of this manufacturing and construction tool.

The Best Clamps: Our Picks

Buying Guide

For those who enjoy woodworking or love to do metalwork, the use of clamps is ideal for joining different materials together and working with ease. In this section you will learn about the advantages of clamps, the different types of materials they are made of and the costs they can have.

What is a clamp and what are its advantages?

Clamps are tools that allow two objects to be firmly clamped together so that they can be worked on together. This equipment is very useful when clamping or gluing materials such as metal, wood or plastic, to name a few. Most clamps have an adjustable screw and a clamping face.

Clamps are used in various branches of work including carpentry, wood carving, furniture making, welding, construction and metalworking. This is due to the large number of clamp models available on the market depending on the size and type of materials to be joined together.

  • They come in various sizes and shapes
  • They can hold various materials
  • They help to do a job safely
  • Depending on the model they can be economical
  • They can be difficult to use
  • If they are not coated they can damage the material they hold
  • They must be handled with care to avoid accidents

C Clamps, F Clamps, H Clamps, Parallel Clamps, Quick Action Clamps, Locking Clamps, Wood Handle Clamps, Corner Clamps and Edge Clamps – What should you look out for?

As we have mentioned, there are a large number of clamps on the market depending on the job to be done. In fact, many experts group them in 38 different models, but, in general, 5 models are the most used. These are: type C, type F, type H, Quick Action and Lock,

Type C clamp. This is the standard clamp as it is the most commonly used. As the name suggests, it has a C-shape together with a clamping screw. Due to its popularity, the C-Clamp can come in various forms and is ideal for a variety of materials and applications from woodworking to metalworking.

F-Clamp. The F-Clamp has a larger opening capacity than the C-Clamp. The F-Clamp has a sliding bar that allows easy adjustment of the tool’s opening capacity in order to clamp thick materials.

Type H clamp. Similar to the F clamp, the H clamp is used for pipe work. This clamp can be placed on a surface for added security. Its mechanism employs a sliding tube instead of the bar. This allows the pipe clamp to adapt to whatever opening capacity you need.

Quick Action Clamp. This type of clamp is also one of the most commonly used clamps due to its mechanism; it can be tightened with one hand by simply pumping the push handle. The opening of the clamp can vary and they are similar to the F clamps.

Locking Clamp. Popular for metal work, especially welding, this clamp has a square clamp shape and has a safety mechanism to prevent it from opening when working with the clamp. They can be operated with one hand for ease of use.

Buying criteria: factors that allow you to compare and rate different models of Clamps

The use of tools such as clamps has enabled the carpentry and metalworking industry to perform work with unparalleled quality and improved safety measures. But before you go out to buy your clamp set, you should know certain factors that will make your purchase safer.

  • The material to be clamped
  • The safety factor
  • The size of the clamp

Each of these factors will be developed in more depth so that you have a more precise and concise way what to look for when you want to buy the best clamp for your work.

The material to be clamped

The use of clamps allows us to clamp different materials to work on them and join them permanently. Depending on the material we are going to work with, the market offers us different clamps that help us to take care of it at the moment of fastening.

Metals. In the case of working with metals, it is best to use metal clamps. This is due to the fact that it is possible that welding or any other work where the material must be heated will be carried out. If we use a clamp made of a different material, we run the risk of damaging it due to the heat emanating from the metal.

Soft Materials. If we are going to clamp wooden, paper or plastic parts, we must use clamps made of wood or plastic. This is because this type of tool usually has a coating at the clamping point that prevents the material from being damaged by the pressure exerted by the clamp.

Usually clamps only need to be clamped correctly on the material to be worked on, but there are models of clamps that have a safety mechanism that guarantees that they will not move and release the material under any circumstances.

It is advisable to purchase this type of clamp as it provides an additional safety factor to the work to be carried out. Remember that incorrect handling can have consequences for both your work and your personal safety.

The size of the clamp

This purchasing factor will be determined exclusively by the size of the material to be clamped. It is best to have a tool that will allow you to clamp both small and large objects.

In this case, it is recommended to purchase F-shaped clamp models, as this type of clamp offers a high clamping range, as well as an adjustment for small items and is the most practical form of clamp available on the market.
