Metaklett (from , "metal" and , "Velcro ribbon") is a
fastening material made of steel that acts on a similar principle to conventional
hook and loop fastener
Hook-and-loop fasteners, commonly known as Velcro (a Generic trademark, genericized trademark), hook-and-pile fasteners or touch fasteners are versatile fastening devices that allow two surfaces to be repeatedly attached and detached with ease ...

shear strength
In engineering, shear strength is the strength of a material or component against the type of yield or structural failure when the material or component fails in shear. A shear load is a force that tends to produce a sliding failure on a mater ...
35 tonnes per square meter at temperatures up to 800 °C. It consists of two complementary strips of 0.2 mm thick perforated steel with catcher and holes. A second variant consists of two strips with protruding brushes and hooks. There is also a hybrid variant with one metal and one synthetic fleece ribbon.
In the context of the development Dr. Christoph Karl Hein compiled his dissertation "Systematic analysis to metallic hook-and-loop bondings".
