What is the appropriate length of rivets to be used for a repair of two pieces of 0.040-inch aluminum?

To determine the appropriate length of rivets for repairing two pieces of 0.040-inch aluminum, it's important to consider the total thickness of the materials being joined and the specifications for rivet length in relation to that thickness. Each piece of aluminum is 0.040 inches thick, so when two pieces are joined, the combined thickness is 0.080 inches.

Rivet length should typically provide adequate grip on both materials while allowing for sufficient head engagement and enough protrusion of the tail to ensure proper deformation during the riveting process. For aluminum materials, it's common to add 1/32 inch to the total thickness as a guideline for selecting rivet length. Therefore, in this scenario:

• Total thickness = 0.040 inches + 0.040 inches = 0.080 inches

• Adding the recommended 1/32 inch (which is 0.03125 inches) results in a total of approximately 0.11125 inches.

When converting this to standard rivet sizes, a rivet length of 1/4 inch (0.25 inches) would be suitable, providing enough length to secure the two pieces together effectively without being excessively long. This length allows for good deformation and a secure joint, maintaining
