What type of bolt is an AN73 bolt?

AN73 bolts are specifically classified as Airforce-Navy machined bolts. This classification indicates that they conform to military specifications set by the U.S. Air Force and Navy, which ensures they meet rigorous standards for performance and reliability in aviation and aerospace applications.

The designation 'AN' typically stands for 'Army-Navy,' referring to materials and parts produced to military standards, suggesting that these bolts are machined with precision for high-strength requirements essential in aircraft assembly.

Understanding that AN73 bolts are designed for specific applications within the aerospace industry also underscores their importance in maintaining safety and structural integrity in aircraft. This classification contrastively differentiates them from standard hex bolts, which may not adhere to the same stringent specifications, and structural bolts, which may have different design characteristics not specific to the military. Locking bolts are intended for preventing loosening due to vibration but do not share the specific military standards associated with the AN73 classification.
