Which head mark indicates 2024-T aluminum alloy?

Explanation:
Rivet head marks identify the alloy and temper of aluminum rivets used in aircraft structure. The raised double dash on a rivet head is the symbol that indicates 2024-T alloy. This alloy is a high-strength aluminum-copper material used where greater strength is needed, and the T denotes a heat-treated temper. Knowing the correct head mark helps ensure you replace rivets with the same material and temper to maintain the intended strength and corrosion behavior. Other head marks correspond to different alloys or tempers, so they would not indicate 2024-T.
