Researchers design steel analog of well-known fastener
Hook-and-loop tape is the generic name. But everyone knows the plastic fastener that can be reused and repositioned endlessly as Velcro. Now, German engineers have developed industrial-grade analogs for automotive and other applications. Made from steel, the newly patented fasteners can operate at temperatures as high as 800° Celsius and at tensile loads of up to 35 metric tons per square meter.
