Close Type Blind Rivet

When installing the close type blind rivet, a special riveting tool is used to pull the mandrel. As the mandrel is pulled, it exerts force on the inside of the rivet body, causing the body to expand and deform. The closed end of the rivet prevents the material from protruding or escaping during the deformation process, ensuring a neat and clean fastening. Eventually, the mandrel is broken off at a predetermined point, leaving the deformed rivet body to firmly connect the two or more workpieces together.

The Close Type Blind Rivet, also known as a sealed or watertight blind rivet, is a specialized fastener designed to create a secure, leak-proof joint in applications where moisture, gases, or contaminants must be excluded. Unlike standard open-end rivets, its mandrel and body are fully enclosed, ensuring a sealed hole after installation.

Key Features:

Watertight & Airtight – The closed end prevents fluid/gas penetration, ideal for HVAC, automotive, or marine environments.

Vibration-Resistant – High clamp force and mandrel retention enhance durability.

Material Options – Available in aluminum, steel, stainless steel, and Monel for corrosion resistance.

Easy Installation – Installed using standard rivet tools, with no need for rear access (blind-side fastening).

Applications:

Automotive panels & fuel systems

Electronics enclosures (IP-rated protection)

Aerospace components

Plumbing and refrigeration systems

Advantages:

Eliminates the need for additional sealing (e.g., gaskets or adhesives).

Maintains structural integrity under pressure/vibration.

Standards: Complies with DIN 7337, ISO 16582, and industry-specific certifications.

Note: Requires compatible rivet tools for proper installation without compromising the sealed end.
