A C-clamp is a sort of clamping tool that is used to hold wooden or metal workpieces in place and is especially useful in carpentry and welding. You can use them to hold two objects in place or to combine two or more materials.

When it comes to learning about the different types of C clamps, it is not uncommon to become confused. Because it’s been stated that there’s a clamp for every job imaginable. If you explore the internet for C clamps, you will find that they come in a variety of shapes and sizes depending on their project requirement.

C clamps are devices that apply inward pressure to securely hold any material or object to prevent displacement. C clamp gets its name from its shape which exactly looks like the letter “C”. It is often known as the “G” clamp. Generally steel or cast iron are used for making C clamps.

You can use C clamps everywhere including woodworking or carpentry, metalwork, manufacturing, as well as hobbies and crafts like robotics, home renovation, and jewelry making.

It is literally IMPOSSIBLE to get a woodworking or clamping job done without a clamper. Yes, you might get by one or two tasks but you won’t be able to get a project up and ready without one of these.

Clamps work as a substitute for your hands when you a bit too much to deal with. There’s only of them (hands) that you’ve got after all. These add stability to your unfinished project, keeps the workpieces from falling off while you’re still working on it.

They might all be the same, but the best C clamps pack more functionality than the others on the market. Here are a quick guide and a short list to have you up and ready with the most functional and ergonomic c clamp.

Guide to Best C Clamps

Here are a few effective tips to keep you company. This way you won’t be lost in finding your next C Clamps.



Steel…… one-word “STEEL”, that’s the best when it comes to rigidity. Yes, the steel ones do cost a bit more and even might seem expensive. But it’ll be worth every penny when you’ll be using it for years having your clamp undamaged.

You’ll find many aluminum clamps that might be cheaper but it’ll bend right away.


Brand value is always a priority. Top brands have their products go through intense quality control before they land on the market. IRWIN and Vise-Grip are two of the kingpins in the clamp universe.

Swivel Pads

Yeah, do keep it in mind. Most come with swivel pads except for a few. One that has swivel pads makes working a lot easier. The work exquisitely on holding workpieces that are in a bit of an awkward position. Well, if it requires to hold the corner of the workpiece, transferring the authority to a corner clamp should be the wisest of choices.

Adjustable Jaw Length

Quite a few of C-Clamps that have a fixed jaw length, like pliers. But these are a huge no-no. Having adjustable jaw length makes it possible for you to get a grip on the pressure that the clamps applying. And even it makes clamping a bit quicker.

Quick Release

You’ll see some clamps that have a quick press button that releases the clamp instantly upon being pressed. This makes clamping a one-handed job and you work a lot easier.

Very few of the C-Clamps that you’ll find on the market will have durability issues. So, basing on the functionality that each clamp provides, I’ve listed down quite a few of them. This way you’ll find one that suits your choice quite quickly.

It holds on to the workpieces tightly without any probability of it slipping off or anything. Swivel jaw pads work amazingly in holding workpieces that make the surfaces unparallel. The jaws rest on a law resistance ball for 360 degrees rotation. To apply pressure, it utilizes a socket joint.

This clamp serves only one purpose but it can definitely be used in different scenarios like you could be using this for welding too. It can be done so because of the chrome plated Acme-threaded screw and the iron frame. Being chrome plated the hot debris flying off during welding won’t permanently stick to the screw.

When it comes to the versatility of this C Clamp has a level of its own. With a throat depth of 2-5/8 inches, it can gulp in a lot of the workpieces to hold on pieces far from the edge. You can find this clamp in different clamping capacities starting from 1 inch to 12 inches.

Screw’s double threaded, this reduces the odds of the of your workpieces drifting away. Even the swivel is larger and takes up any required orientation. The versatility increases even more due to the entirety of the frame being made out of iron. The iron that can withstand the heat of welding.

Chances of scratches or marring on your workpieces is greatly reduced by the larger surface area of contact of the swivel pad.

Pro-Grade, that’s the name of the manufacturer. It’s not a quite heard of name in the hardware and tools arena, but still, it’s uniqueness made me put it on the list. It’s a 3-way c-clamp, more of an E-clamp. You’ll understand what is it that um talking about once you take a good look at the picture.

The jaw gap can be a maximum of 2½ inches.  And so is the throat depth, 2½ inches. The dimensioning is optimum for woodworking projects and welding.

Durability is quite unquestionable too. Pro-Grade is giving a lifetime warranty. They’ve coated the body of the clamp with a black oxide coating. And yes, they too have given all three of the movable screws swivel pads. So, you know that this’ll be a great piece of equipment for working with workpieces of uneven surfaces.
