This type of fastener comes with different materials, such as in aluminum, zinc coated steel, copper steel and many more. The rivet assembly is inserted into a hole drilled through the parts to be joined, and a specially designed tool is used to draw the mandrel into the rivet.
These blind rivets have non-locking mandrels, and are sometimes avoided for critical structural joints. The mandrels may fall out, due to vibration or other reasons, leaving a hollow rivet that has a significantly lower load carrying capability than solid rivets.
