The shank of a lockbolt runs from which point of the head to the tip of the bolt?

The shank of a lockbolt is defined as the portion that runs from the bottom of the head to the tip of the bolt. This is crucial because the shank is the main body of the bolt that provides structural integrity, strength, and allows for engagement with the materials being joined.

Understanding that the shank starts at the bottom of the head clarifies its function in applications where the lockbolt is used to fasten parts together securely. The head serves as a bearing surface and provides a means to apply torque, while the shank must be of appropriate length and diameter to ensure effective load transfer and clamp force. Thus, knowing the correct orientation of the shank is essential for proper installation and achieving the desired performance in aerospace applications.
