For joining two sheets of .032-inch aluminum, which rivet should be selected?

When selecting a rivet for joining two sheets of .032-inch aluminum, the specifications and designations of the rivets must be considered. The chosen rivet, MS20470AD-4-4, is specifically suitable for this application due to its size and material properties.

The "4" in the MS20470AD-4-4 designation indicates the diameter of the rivet, which is about 1/8 inch, and the rivet is designed for use with materials that have a thickness of around .040 inches to .063 inches. Since the combined thickness of the two .032-inch aluminum sheets is .064 inches, the rivet's appropriate grip range makes it ideal for this particular application.

In contrast, the other rivets listed may either have a larger diameter than necessary or are not well-suited for the joint configuration or material thickness. For example, the other options either indicate a larger diameter or grip length that does not align with the requirements for effectively joining .032-inch sheets. Therefore, the option selected provides the best fit in terms of diameter, grip, and type for aluminum, ensuring structural integrity in the assembly.
