The markings on the head of a Dzus fastener provide information on which of the following?

The markings on the head of a Dzus fastener are specifically designed to convey critical information about the fastener itself. These markings typically indicate the body diameter, type of head, and the length of the fastener, which are essential characteristics for ensuring the fastener fits properly within the assembly and performs its intended function.

Understanding these dimensions is crucial when selecting fasteners for sheet metal structures, as using an incorrect size can lead to assembly issues or failures in structural integrity. Therefore, being able to read and interpret the markings correctly enables technicians and engineers to choose the right fasteners for their applications, ensuring proper installation and maintenance of aircraft structures.
