We report a highly reversible and robust micro-zip fastener based on the van der Waals force-assisted interlocking between rectangular parallelepiped arrays with simple geometries. To investigate zip-like interlocking behaviours, various line arrays were fabricated with three different spacing ratios (1, 3, and 5 of 800 nm in width), feature sizes (400 nm, 800nm, and 5 μm in width with the spacing ratio of 1). In addition, the different rigidity of line arrays was inspected. The measured normal and shear locking forces was demonstrated to depend on the material rigidity as well as geometric parameters, in good agreement with a proposed theory based on the percentage of area in contact and force balance. The maximum adhesion forces as high as ~8.5 N cm<SUP>-2</SUP> in the normal direction and ~29.6 N cm<SUP>-2</SUP> in the shear direction was obtained with high stability (during <1,000 cycles). Furthermore, the study for high stability of the fastening system was conducted to prevent critical failures such as buckling and fracture for practical applications.
