    Abstract: A mechanical fastening system for a diaper or like disposable garment of a male mechanical fastening tab (e.g., a hook-type fastener) attached to a corner or edge region of the garment with a mating fibrous web on an opposing corner or edge region. The male mechanical fastening tab creates two areas of attachment, an outward portion extending beyond the first corner or edge region and an inward area extending inward of the first corner or edge region, where both areas of attachment engage the fibrous web on the opposing corner or edge. The male mechanical fastening tab with the fibrous web creates a secure non-rotational attachment using a single fastening tab.
