Bar clamps are available in various lengths and provide greater reach than C-clamps, allowing them to accommodate wider workpieces.

Pipe Clamp

Pipe clamps are customizable clamps made with a pipe and adjustable jaws. They are highly adjustable, as the length depends on the size of the pipe you use. This makes them popular for large-scale woodworking projects like furniture building, where they can hold boards and panels together tightly.

Spring Clamp

Spring clamps are quick-release clamps with a spring-loaded mechanism that makes them easy to use with one hand. These clamps are small and offer a moderate amount of pressure, making them great for light-duty tasks like holding fabric, gluing small items, or securing objects temporarily. They’re popular for crafts and DIY projects due to their ease of use.

Corner Clamp

Corner clamps, or right-angle clamps, are specifically designed to hold two pieces of material at a 90-degree angle, making them perfect for framing, box construction, and cabinetry. They’re commonly used in woodworking for aligning corners and ensuring a perfect fit when joining two pieces.

Toggle Clamp

Toggle clamps feature a quick-release lever and are typically mounted on a workbench or jig. They’re commonly used in repetitive or production work because they’re fast and easy to operate. Toggle clamps come in various styles, such as horizontal, vertical, and push-pull, and are often used in woodworking, metalworking, and industrial applications.

Bench Vise

While technically not a clamp, a bench vise acts similarly by holding materials steady. It’s permanently attached to a workbench, allowing it to securely grip wood, metal, or plastic while you work. Bench vises are popular in woodworking and metalworking because of their stability and strength.

Hand-Screw Clamp

A hand-screw clamp has two wooden jaws connected by threaded rods that allow for precise adjustment and uniform pressure. These clamps are commonly used in woodworking, as the wooden jaws won’t damage delicate surfaces, and they provide a strong, even grip on irregularly shaped objects.

Ratchet Clamp

Ratchet clamps have a ratcheting mechanism that allows for incremental tightening, providing strong pressure with a quick-release feature. They’re similar to bar clamps but are faster to adjust, making them useful for general-purpose clamping in woodworking and DIY projects.

Strap Clamp

Strap clamps, or band clamps, are adjustable clamps with a long nylon strap that wraps around irregularly shaped objects. They’re often used for circular or multi-sided pieces, like frames, furniture, or boxes, where even pressure around the entire object is necessary.
