What is the recommended approach if a rivet set does not fit a specific rivet type properly?

The recommended approach of obtaining a new rivet set with the correct radius is essential for ensuring the integrity and strength of the riveted joint. Using the correct rivet set is critical because it helps to accommodate the specific rivet type, allowing for proper deformation of the rivet during installation. This deformation is what creates the necessary mechanical interlock between the rivet and the materials being joined, which is vital for load-bearing applications.

Using a hammer to adjust the set is not advisable because it may lead to damage or alteration of the metal set which will not provide the desired fit for the rivets, potentially compromising the quality of the installation. Avoiding the use of that rivet type altogether doesn't address the underlying issue and could limit design options. Simply increasing the size of the hole alters the specifications and also does not resolve fitment issues, which could lead to structural weaknesses or even failure of the joint.

In contrast, selecting the correct rivet set ensures that all aspects of the installation conform to engineering standards, promoting safety and reliability in the finished assembly.
