What component is part of the Dzus turnlock fastener system?

The Dzus turnlock fastener system is specifically designed for quick and efficient access to panels or components on aircraft. One of the critical components of this system is the stud. The stud is threaded and is installed on the structure or panel, allowing it to accept the Dzus fastener mechanism. When the turnlock is engaged, it securely holds the panel in place by fastening it to the stud.

This design provides an easy way to install or remove access panels without the need for tools, thereby enhancing efficiency during maintenance operations. The simplicity and reliability of the stud's design contribute to the overall functionality of the Dzus fastener system, making it widely used in aviation engineering.

In contrast, while clamps, pins, and lock washers may serve various fastening or securing purposes in different applications, they are not integral components of the Dzus turnlock fastener system itself. Therefore, the stud's unique role in this specific fastening mechanism is why it is the correct answer.
