Which of the following is the main advantage of rivets in steel construction?

Concepts:

A rivet has a cylindrical shank with a head at one end. It is used to make permanent joints between two plates. Rivet is inserted into the holes of plates (which are to be joined) and then its protruding part is upset by a hammer.

Advantages of Rivet connection:

1. It is more reliable
2. It can also be used for non ferrous metals
3. Parts assembled by Riveted joint do not have any thermal after effec
4. Its quality inspection is easy and cheap
5. When parts are dismantled riveted parts have less damage compared to welded parts 
6. They have good vibration damping capabilities so where required rivets are used in place of it

Disadvantages of Riveted joints

1. Due to holes plates become weak.
2. Labor cost is more as more and skilled workforce is needed.
3. Overall cost of riveted joints is more.
4. They have more weight than welded joints.
5. Riveting process creates more noise.
6. Stress concentration near holes.
