What can be a consequence of not using a properly sized rivet set?

Using a properly sized rivet set is crucial in ensuring the integrity of the rivet installation process. When a rivet set is not sized correctly, one significant consequence is the potential compromise of the rivet head. A rivet set that is either too large or too small can lead to improper deformation of the rivet head during the peening process, which may result in a weak connection. This improper formation can make the rivet head unable to effectively bear load, potentially leading to failure during operation.

A correctly sized rivet set ensures that the rivet is compressed evenly and solidly, creating a strong mechanical bond between the materials being joined. Inadequate contact can lead to an insufficiently formed head, which compromises the strength and reliability of the assembly.

While it is true that other issues, such as a rivet slipping out, becoming loose, or not penetrating completely, can occur due to various factors including incorrect installation technique or insufficient force, the compromise of the rivet head itself is a direct consequence of using an inappropriate rivet set.
