Wood clamps are a core component of any DIY-er’s tool kit and essential for performing the majority of woodworking projects. These invaluable tools have adjustable jaws for holding wood pieces together, and they come in a wide range of sizes and types. Whether you’re assembling smaller items like a picture frame or cutting board, or larger projects like doors and tables, wood clamps ensure that all the pieces are positioned exactly how you want them and won’t shift out of place while you nail, screw, or glue them together. Thanks to their simple operation and impressive strength, wood clamps make it possible for a single person to tackle even large projects solo.

Wood clamps are not one-size-fits-all, so make sure you choose the right type for the job. Compact spring clamps are suitable for smaller, light-duty tasks, while larger bar clamps are a better option for wider applications like cabinetry or drawer construction. Pipe clamps offer the most width–you’re only limited to the length of pipe being used–and are essential for extra-large jobs, like oversize tables and doors.

Another factor to consider is the type of wood you’re going to clamp. If you’re working with finished or delicate pieces, choose a clamp that won’t leave unsightly dents or scratches in the wood surface. Clamps with extra padding, or that have jaws with a lot of surface area, are less likely to damage a workpiece while still providing enough pressure to be effective. It’s worth noting that you can also add your own padding, like wood shims or scraps, to clamps, although it can be inconvenient and sometimes difficult to ensure no pieces slip out of place.
