metallklemme

A metallklemme, or metal clamp, is a fastening device used to secure two or more pieces of material temporarily during machining, assembly, welding, or inspection. It applies controlled pressure to hold parts in alignment or prevent movement while work is performed. Clamps are designed to be removable and reusable, and they come in many sizes and configurations.

Most metallklemmen consist of a rigid frame and a movable jaw operated by a screw, lever, toggle, or hydraulic mechanism. Common forms include C-clamps (screw clamps with a threaded screw and swiveling jaw), bar clamps and pipe clamps (long bars or pipes with adjustable jaws), locking pliers (adjustable clamps with a locking mechanism), and toggle clamps (fast-acting clamps used in workholding).

Frames are typically steel or cast iron, sometimes aluminum for light-duty use. Clamping jaws are hardened steel or alloy, with replaceable surfaces. Finishes may include zinc plating, black oxide, or powder coatings to resist corrosion. The choice of mechanism affects ease of use, holding power, and quickness of operation.

Metallklemmen are used in metalworking, woodworking, electronics assembly, and construction. Operators should select the correct size and clamp force for the task, ensure proper alignment, avoid overtightening to prevent workpiece or jaw damage, and use protective pads to prevent marring.

While simple, clamps are essential tools in workshops, offering repeatable pressure and holding power. They are often sold in sets that include several types to accommodate a range of tasks.
