Countersunk blind rivets, also known as flush-head rivets, are specifically designed to sit flush with or slightly below the surface of the material.
They are the standard choice for applications where a protruding head would cause interference, such as in sliding tracks, or where a smooth, aerodynamic finish is required, such as on aircraft skins or automotive panels.
Key Features & Installation
Installing these rivets requires more preparation than standard dome heads because the material must be modified to accept the cone-shaped head.
120° Head Angle: Most countersunk blind rivets follow a standard 120-degree head angle. This is wider and shallower than the 82° or 90° angles typical for screws, and different from the 100° angle used for solid aviation rivets.
Hole Preparation: To achieve a perfectly flush finish, you must use a 120° countersink bit to create a conical recess in the top sheet.
Material Thickness: The top sheet must be thick enough to accommodate the countersink depth (often at least 1mm).
