metallkläm

A metallkläm, or metal clamp, is a mechanical device used to hold components together or secure a position by applying pressure through two jaws. Made primarily from metal, such clamps rely on a screw, lever, or quick-release mechanism to generate clamping force. They are designed for repeated tightening and release, providing stable, temporary fixtures during assembly, machining, or transport.

Materials and construction vary, with common options including steel, stainless steel, and aluminum. Steel clamps offer high strength and durability, while stainless steel provides corrosion resistance for challenging environments. Finishes such as zinc plating or anodizing are often applied to improve wear and corrosion resistance. Jaw surfaces may be smooth or padded to minimize damage to delicate workpieces.

Common types include screw clamps (C-clamps or G-clamps) that use a threaded screw to move the jaw, bar or pipe clamps with a sliding arm for longer reach, and toggle clamps that lock with a quick-action lever. Spring clamps provide fast, temporary holding without threaded adjustment. Hose or band clamps, including worm-drive varieties, secure circular objects such as hoses or tubes.

Applications span woodworking, metalworking, electronics mounting, automotive repair, and plumbing. Key specifications to consider are clamping force, throat depth (the distance the fixed jaw can reach before contact), maximum opening, and jaw pad design. Proper use involves avoiding over-tightening to prevent damage and selecting corrosion-resistant materials for outdoor or wet environments. Regular inspection for wear and corrosion helps maintain reliability.
