Which type of rivets is appropriate for joining two sheets of .032-inch aluminum?

The selected rivet type, MS20470AD-4-4, is appropriate for joining two sheets of .032-inch aluminum due to the specifications and sizing involved in its designation. The MS20470AD series of rivets are designed for use in structural applications and have different sizes that correspond to varying thicknesses of materials.

The "AD" indicates that it is an aluminum alloy and the numbers that follow indicate the diameter and length of the rivet, both in units of 1/32 of an inch. In this case, the '4' refers to a diameter of 1/8 inch (since 4 multiplied by 1/32 equals 1/8). The length designation of '4' indicates that the rivet is also specifically sized to accommodate materials of certain thicknesses. For the MS20470AD-4-4, the rivet length is suitable for thicknesses around .032 inches to .080 inches when joining aluminum sheets.

In comparison, the other options present rivets with different diameter and length specifications that would not be as suitable for just .032-inch aluminum sheets. Larger rivets could be too thick and potentially damage the material or create an improper fit, while smaller rivets might not provide
