Which rivets are recommended to join two sheets of .032-inch aluminum?

When joining two sheets of .032-inch aluminum, the recommended rivet size takes into account the thickness of the materials being joined and the appropriate grip length needed for a secure connection. In this case, the .032-inch thickness of each aluminum sheet results in a total thickness of .064 inches when two sheets are stacked together.

The MS20470AD rivets are designed with various grip lengths, indicated by the final number in the designation. The grip length needs to be sufficient to ensure that the rivet fully engages with both sheets without being too long or too short. For the combined thickness of .064 inches, a rivet with a grip length of 4-4, which represents a range that accommodates slight variations in sheet thickness, is suitable for proper fastening.

Using a rivet with a grip length of 4-4 ensures that it fits snugly and securely, allowing for proper deformation during installation, which creates a strong joint. The selected rivet size helps to prevent issues such as inadequate clamping force or potential failure of the joint due to excessive spacing.

The rationale for the other options lies in the varying grip lengths; some are too short or too long for the thickness of the sheets being joined. Thus, the choice of
