When the rivet is installed, the body disrupts on the blind side in a way that forms three petals which extend away from the mandrel head. This makes this rivet ideal in out-of-round or oversized holes. The rivet requires less pulling force during installation than a standard blind rivet which makes it useful in thin, soft or brittle materials. Each size has a relatively wide grip range and is corrosion resistant. These rivets have dome heads.
