Describe how the pop rivets work
What will be an ideal response?
The pop rivet was named because it makes a popping sound when installed. It is useful in situations
where it is difficult to hold one end of the rivet and hammer the other. The pop rivet appears to be
mostly stem. During installation, the special pop rivet tool pulls the stem until the head (ball-like)
forces the end of the rivet to expand. By expanding, the rivet is held into place. As the stem is pulled
further by the tool, it breaks with a popping sound.
