What is the portion of a key between the shoulder and the bit called?

Neck of Key

The portion of a key between the shoulder and the bit is referred to as the neck of the key. This section serves an important purpose as it helps to provide structure and stability to the key, ensuring it fits properly into the lock mechanism. The shoulder is the part of the key that prevents it from being fully inserted into the lock, while the bit is the area that interacts with the lock's pins or wafers to enable the locking mechanism to operate. The neck connects these two critical areas and is designed to maintain the key's integrity during use. Understanding the anatomy of a key, including its neck, is essential for locksmiths as it helps them in key duplication and lock installation processes.
