Countersinks are identified by which of the following characteristics?

Countersinks are primarily identified by characteristics that include the size of the body, the angle, and the size of the pilot. The body size pertains to the diameter of the countersink, which determines how it will fit into the workpiece and accommodate the fastener. The angle refers to the conical shape of the countersink, which is essential for allowing the head of the screw or bolt to sit flush with the surface of the material. Lastly, the size of the pilot is significant because it allows the drill bit to accurately create a starting hole that corresponds to the countersink, ensuring proper alignment and fit during assembly.

This focus on the specific aspects of countersinks provides the necessary details for selecting the correct type for different applications, making these characteristics crucial for successful aerospace assembly.
