Most pneumatic staplers use compressed air to force the staples into a variety of surfaces, such as wood or metal at an extremely high speed. They use heavy-gauge metal staples. The most common staple dimensions fall between 1/4 inches (about 6.5 mm) to 1/2 inches (about 13 mm) in width, and 3/8 inches (about 9.5 mm) to 1-1/2 inches (about 38 mm) long. The curved shape of staples holds the material in two places, so they have potentially strong holding power.
