Overview:
The different blind rivet heads
Blind rivets differ not only in material and size, but also in their head shape. Choosing the right head shape is crucial for the strength and reliability of the connection. In this guide, we present the most common types of rivet heads and provide practical tips for their use.
What is a rivet head?
A rivet head is the part of the blind rivet that remains visible after setting and ensures the stability of the connection. Choosing the right head shape is essential to get the best possible performance from the rivet and to avoid affecting the appearance of the workpiece. There are three main types of rivet head, which we will explain below.
The three main head shapes of blind rivets:
Dome head (flat head):
The flat head is the most common head shape among blind rivets. It offers a large contact area on the material, ensuring an even load distribution. This type of rivet head is particularly suitable for thin and easily deformable materials, as it provides a good hold without putting excessive strain on the material. The flat head is often used in the construction and metalworking industries, where a robust and stable connection is required.
Countersunk head:
The countersunk head is used when a smooth surface is required. This head shape is conical and protrudes less from the material than the flat head after the setting process. This makes the countersunk head ideal for applications where the riveted component must be flush or comes into contact with other components. Typical areas of application are in the automotive industry or electronics, where a flat surface is crucial.
Large flange:
The large flange is characterized by a larger bearing surface and is used in applications where sensitive materials or high loads are processed. Thanks to the large bearing surface, the material is better protected and a stable connection is created that can withstand higher loads. This head shape is often used in the furniture industry or in larger construction projects where the durability of the connection is a priority.
How do I choose the right rivet head for my project?
The choice of the right head shape depends on several factors:
- Flat head: Ideal for thin or easily deformable materials.
- Countersunk head: Perfect for flush surfaces or applications where the rivet must not be disruptive.
- Large flange: Optimal for sensitive materials or high loads.
When making your selection, ask yourself whether the material is particularly strong or delicate, whether the connection will remain visible or should be flush, and how much load the rivet will have to bear.
Can rivet heads be reused?
Blind rivets and their head shapes are generally designed for single use. After they have been set, they cannot be reused because the rivets are deformed by the setting process. However, if you need to loosen a connection, special tools can be used to remove the rivets before inserting a new rivet.
What do I need to set a rivet head?
To set blind rivets, you need the appropriate riveting pliers. Choosing the right riveting pliers depends on the size and type of blind rivet. GESIPA offers a wide range of tools and accessories to help you create the best possible connection for your project.
