What type of snap ring pliers are specifically designed to allow for the installation of expanding snap rings?

Internal
External
Adjustable
Locking

The correct answer is: External

Expanding snap rings, which are often used in various mechanical applications, require a specific type of tool for effective installation. The correct choice focuses on external snap ring pliers, which are designed to grasp and expand the rings from the outside. This type of pliers allows the user to expand the snap ring easily, facilitating its placement into grooves or around assembly components. Internal snap ring pliers, on the other hand, are intended for placing or removing rings that fit inside a component, making them unsuitable for expanding snap rings. Adjustable and locking pliers serve different purposes and are not specifically designed for the unique geometry and function of expanding snap rings. External snap ring pliers thus provide the necessary grip and expansion action needed for efficient installation, making them the correct choice for this application.
