What is the nickname given to DD rivets that are annealed and stored in the freezer?

The nickname given to DD rivets that are annealed and stored in the freezer is "Ice box rivets." This term stems from the practice of storing certain types of rivets in a cold environment to extend their shelf life and maintain their mechanical properties. When DD rivets are annealed, they are softened through a heating process, and then cooling them in a freezer inhibits unwanted reactions that could affect their performance during installation and afterward.

This cold-storage technique preserves the rivets' effectiveness, as they are less likely to age and lose quality when kept at low temperatures. While the other terms may describe similar practices regarding temperature management, "Ice box rivets" specifically denotes the combination of the annealing process and the storage method used to ensure the rivets retain their optimal performance characteristics.
