What is a common disadvantage of using solid rivets compared to pop rivets?

Using solid rivets does indeed require access to both sides of the joint, which can be a significant disadvantage compared to pop rivets. Solid rivets are installed by being deformed (commonly by hammering or using a special tool), which necessitates that the rivet be accessible on both the head and tail ends. This can make the installation process more challenging, especially in situations where one side is inaccessible.

In contrast, pop rivets can be installed from one side, making them much more versatile for applications where space or accessibility is an issue. This one-sided accessibility is particularly valuable in automotive and construction situations where parts might be stacked or enclosed.

The other choices, while they may point out issues with solid rivets, do not directly address the core logistical challenge brought about by the necessity of having access to both sides of the joint, thus highlighting the particular advantage of pop rivets in terms of application versatility.
