COUNTERSUNK HEAD

COUNTERSUNK HEAD

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).
