What exactly is the function for the Helen Keller bolts on a c-130 leading edge?

The Helen Keller bolts on a C-130's leading edge serve as a mechanical fastener that connects and secures the leading edge flaps to the wing structure. These bolts are designed to allow for controlled movement of the flaps, which contribute to the aircraft's aerodynamic performance during takeoff, landing, and low-speed flight. Named after Helen Keller, they are crucial for ensuring the safety and functionality of the aircraft's wing configuration.
