Electric rivet guns are indispensable tools for fastening materials efficiently and securely. The type of rivet used with these guns plays a critical role in the quality and performance of the joint. This article explores the different types of rivets available for electric rivet guns, providing guidance on selecting the appropriate rivet for specific applications.

Blind Rivets

Blind rivets are designed for applications where access is limited to one side of the material. They consist of a tubular body with a mandrel set inside. When the electric rivet gun squeezes the rivet, the mandrel is pulled into the tubular body, expanding it to form a secure joint. There are various types of blind rivets, including:

– Solid Blind Rivets: These rivets have a solid mandrel that breaks as the rivet is set, leaving a permanent joint.

– Break-Stem Blind Rivets: Similar to solid blind rivets, but the mandrel breaks away after setting, leaving a protruding portion that can be easily removed.

– Multi-Grip Blind Rivets: These rivets have an extended grip range, making them suitable for a wider range of material thicknesses.

– Self-Piercing Blind Rivets: Designed to pierce through thin metal sheets without pre-drilling, offering a fast and convenient solution for fastening lightweight materials.

Structural Rivets

Structural rivets, also known as solid rivets, provide a more permanent and load-bearing connection compared to blind rivets. They consist of a solid cylindrical pin and a separate driven head. The pin is inserted into a pre-drilled hole, and the head is hammered to form a secure joint. Structural rivets are highly durable and resistant to shear and tensile forces, making them suitable for heavy-duty applications.

Tubular Rivets

Tubular rivets are similar to blind rivets but feature a hollow body. When set, the rivet expands and fills the hollow body, creating a tight joint. Tubular rivets are often used in applications where blind riveting is not possible, such as when there is limited clearance behind the material.

Specialty Rivets

In addition to the common types of rivets, there are also specialty rivets designed for specific applications. These include:

– Peel Rivets: Designed to create a low-profile connection, with the rivet head peeling back against the material surface.

– Semi-Tubular Rivets: Similar to tubular rivets, but with a solid head that provides increased bearing surface.

– Corrugated Rivets: Provide a larger grip range and offer enhanced vibration resistance due to their corrugated design.

– Lock Rivets: Feature a locking mechanism to prevent the rivet from loosening over time, ensuring a secure and vibration-resistant connection.
