What are the differences between flat round head rivets and oblate round head rivets?

Rivets are a common fastener and are widely used in various mechanical equipment and building structures. Among them, flat round head and oblate round head are two common rivet head types, each with unique characteristics and applicable scenarios.

1. Shape characteristics

The head of the flat round head rivet presents a flat circle, and its surface is perpendicular to the rivet rod. This head design allows the rivet to fit tightly with the surface of the connector after installation, providing evenly distributed pressure.

The head of the oblate round head rivet presents a flat and slightly arc-shaped shape. Compared with the flat round head, the oblate round head has a larger contact area and can better adapt to the unevenness of the connector surface during installation.

2. Usage scenarios

Due to its flat head and uniform pressure distribution, the flat round head rivet is more suitable for occasions with high requirements for surface flatness, such as the connection of precision mechanical parts and decorative parts with strict appearance requirements.

The oblate round head rivet is more suitable for occasions with certain surface unevenness. Its large contact area and good adaptability enable it to provide a stable connection effect in complex environments.

3. Aesthetics and firmness

From an aesthetic point of view, the flat surface of the flat round head rivet is easier to blend into the surrounding environment, presenting a simple and generous visual effect. However, due to its unique shape, the oblate round head rivet may appear more prominent in certain specific occasions.

In terms of firmness, there is no obvious difference between the two head types of rivets. They can both provide reliable connection effects. The key lies in choosing the appropriate rivet specifications and the correct installation method.

In summary, there are obvious differences between flat round head and oblate round head blind rivets in terms of shape characteristics, usage scenarios, aesthetics and firmness. When choosing, comprehensive consideration should be made based on specific needs and actual application scenarios to ensure the best connection effect.
