    Patent number: 6877646
    Abstract: There is provided self piercing rivet comprising a substantially planar metal body portion (160) having deformable tabs (161) symmetrically disposed about a slit (162) as per the first embodiment. The upper portion of the body portion (160) is provided with a V-shaped recess (163) diverging from a point (164) adjacent the centreline of the body portion (160) and terminating at the upper edge (165) of the body portion (160).
