Woodworking Spring Clamps

Spring clamps are used for quick, light-duty clamping where you need to hold pieces together temporarily without the setup time of screw clamps. Common uses include holding glued joints while the adhesive sets, securing workpieces during assembly, and keeping pieces aligned while you position a heavier clamp. They are ideal for thin materials, small projects, and any situation where you need to apply pressure fast.

Spring clamps are available in small, medium, and large sizes to suit different jaw openings and material thicknesses. Larger jaws give you more reach and can hold thicker materials, while small clamps are handy for delicate work and cramped spaces.

Hammer Roo stocks Timberlock Tools GripMate spring clamps and the Pony Jorgensen set, both known for solid construction and reliable spring tension. The GripMate clamps have padded jaws to protect timber surfaces from marking, which makes them a popular choice for fine woodworking and finishing work where surface damage is not an option.

Spring clamps can assist with small panel glue-ups and thinner timber, but they are not a substitute for parallel clamps or F clamps when significant clamping pressure is needed. They work well as a secondary clamp to stop a joint from shifting while you position your main clamps, or for edge banding, veneer work, and small box assembly.

A spring clamp works on spring tension alone, you squeeze the handles to open the jaws and let go to clamp. An F clamp (also called a bar clamp) has a sliding arm and a screw mechanism that lets you apply significantly more clamping force and dial in the exact pressure needed. Spring clamps are faster to apply and release, while F clamps are better suited to heavy joinery and long glue-ups where controlled, consistent pressure matters.
