Woodworking clamps apply pressure to hold pieces of wood together temporarily. Says Carl Lewis, qualified joiner and owner of DIY website thediyfix.com, “Clamps are extremely useful. They are perfect for holding timber in place while cutting or ripping down the length with a circular saw. They are also extremely useful for holding wooden pieces together as glue or other adhesives dry.”

What to Look for in a Woodworking Clamp
No woodworking shop is complete without a wide assortment of clamps in different types and sizes. Just about any carpentry or woodworking project that goes beyond merely hammering a couple of boards together requires the use of a clamp. But while all clamps serve the same basic function—holding two or more pieces together temporarily—there are many different types of these handy tools available, each with a slightly different use or benefit. Below are some of the more common types of clamps you’ll want to consider adding to your workshop.
C-Clamp: Also called a carriage clamp, these basic clamps resemble the letter “C” and come in a range of sizes, although 4, 6, or 8 inches are the most common. These are useful for holding narrow boards or wood pieces together while glue or another adhesive dries.
Bar Clamp: Also called an F-clamp, due to its shape, the bar clamp opens much wider than a C-clamp, allowing you to hold much larger workpieces together. There are bar clamps as small as 6 inches, but most woodworkers find that 24 to 36 inches is the most useful for large projects.
Pipe Clamp: Also called an H-clamp, these are sets of clamp heads that allow you to use them with any length of pipe needed to create a clamp that’s just the right size for your project. These are handy for a wide range of tasks, including holding edging in place while an adhesive dries.
Trigger Clamp: This is basically a bar clamp that has a trigger for quick and easy opening and closing of the clamp, even with just one hand.
Pinch Clamp: Also called a hand or spring clamp, these simple clamps are useful for holding delicate materials together.
Corner Clamp: This is a specialty clamp that’s designed to hold pieces together at a 90-degree angle. It’s a very useful clamp if you are building picture frames, drawers, or similar items.
Face Clamp: These clamps are something like a pinch clamp, but with a square shape and wide pads that clamp securely without marring a delicate surface. They are useful for holding delicate pieces in place for gluing or drilling.
Clamp/Spreader: These are bar clamps, usually trigger-style, that can be reversed to apply outwards pressure to hold pieces in an extended position, as well as used for clamping pieces together.
Clamps come in a wide range of sizes, allowing you to choose which best suits the size of the material you are clamping. There are a few numbers to consider when it comes to size:
- The overall length of the clamp.
- The jaw opening size, which is the maximum distance the jaws can separate. This determines how wide of an object the clamp can hold. Often, it's the same as the overall length, but not always.
- The throat, which is the depth of the clamp, measuring from the frame of the clamp to the tip of its jaw. This measurement determines how far the clamp can reach into the material being held.
Clamping force is a measurement of how much pressure the clamp can exert when fully tightened. Too much pressure may split or damage the wood and too little pressure might prove ineffective for the job. Look for the clamping force in the specifications of any clamp you're considering.
The material that the clamp is made of will determine its durability. There are light-duty clamps made of resin or anodized aluminum, while heavy-duty clamps will typically be made from drop-forged steel or cast iron.
How do I store woodworking clamps?
You want to store woodworking clamps in a location that is accessible and makes it easy to retrieve them when needed. Some of the best options for storage include a drawer in a tool chest or using a pegboard with hooks to hang the clamps when not in use. Pipe clamps could also be stored on shelf brackets.
Keep your brackets away from moisture and temperature extremes to avoid damage.
How many types of clamps are there?
There are at least 30 different types of clamps to offer various methods of applying pressure. The design of the clamp determines its type, while the material, manufacturer, and warranty of the clamp will impact its cost.
How many clamps do I need to use?
You will need to use at least two clamps for most projects, but the specific number of clamps to use will vary based on the size of what you're working on and the PSI required (largely based on the type of wood you're working on).
