Metaklett, a steely hook and loop fastener

Metaklett is a hook and loop fastener system developed by researchers at TUM, the Technische Universitaet Muenchen. Like Velcro fasteners, Metaklett devices can be easy to secure and release, yet they can withstand very strong mechanical stresses, high temperatures and harsh chemicals.

Hook and loop fasteners have become commonplace features of both industry and households. However, they have one snag: they are too weak for many applications. Hook and loop fasteners made of spring steel have now been developed at the Institute of Metal Forming and Casting of the Technische Universitaet Muenchen. These fasteners are resistant to chemicals and can withstand a tensile load of up to 35 tonnes per square meter at temperatures as high as 800°C.
