A pan head rivet is a type of mechanical fastener characterized by a flat, slightly rounded head with a wide diameter, resembling the shape of a shallow pan. Unlike countersunk rivets, which sit flush with the surface, pan head rivets sit above the surface of the material. They are commonly used when a large bearing surface is needed to hold materials together securely without embedding into the surface.
Key features of pan head rivets:
-
Head shape: Rounded top with flat sides, providing a broad surface for distributing load.
-
Visibility: The head remains visible above the material.
-
Material compatibility: Can be made from steel, aluminum, copper, or stainless steel.
-
Applications: Often used in sheet metal assembly, electronics, automotive panels, and other applications requiring strong fastening without countersinking.
In short, pan head rivets combine strength with a broad bearing surface, making them ideal where flush mounting isn’t necessary but stability and surface area are important.
