A releasable fastener system comprises two hook portions (12,14). The hook portions each include a support (16,20) and a plurality of closely spaced upstanding hook elements (18,22) extending from one side thereof. When the two hook portions (12,14) are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. The head elements (17,21) of the hook elements (18,22) are formed of a material that provides a change in directional orientation of the head elements (17,21). In this manner, the directional orientation of the head elements (17,21) of the hook elements (18,22) can be remotely changed to provide a reduction or magnification in the shear and/or pull-off forces. |
