Closed-End Blind Rivet
Closed-End Copper Blind Rivets with Steel Mandrel
A copper rivet body with a steel mandrel for one-sided fastening in sheet-metal, enclosure, panel, and general workshop assemblies.
Closed-End Construction
The closed body helps limit passage through the center of the fastener. Final joint sealing still depends on hole fit, material condition, and installation quality.
Red Copper Body
Copper provides useful corrosion resistance, electrical conductivity, thermal conductivity, and a distinctive copper appearance.
Steel Mandrel
The steel mandrel provides the pulling element used to set the rivet with a compatible blind-rivet tool.
One-Side Installation
Designed for fastening when only the accessible side of the workpiece can be reached.
Selection note: Choose the exact diameter, body length, and pack quantity shown in the variants. Confirm the prepared hole and total material thickness before installation. Closed-end construction is not an unconditional waterproof, airtight, or pressure-tight guarantee.
Construction
How the Rivet Works
Insert the rivet body into a correctly prepared hole from the accessible side. A compatible blind-rivet tool pulls the mandrel to set the rivet, then the breakstem separates during installation.

Material & Care
Material and Magnetism Notes
Why can this rivet be attracted to a magnet?
The copper body is generally nonmagnetic. Magnetic attraction may come from the confirmed steel mandrel. Magnet response alone should not be used to identify the copper grade or steel grade.
What should I consider in wet or mixed-metal assemblies?
Copper and steel are dissimilar metals. For sustained moisture, salt, or chemical exposure, evaluate galvanic compatibility, drainage, isolation, and joint protection for the complete assembly.
Installation
Basic Installation Guidance
- Choose the exact rivet diameter and body length for the workpiece and application.
- Prepare a clean hole within the size-specific recommendation and remove burrs.
- Insert the rivet from the accessible side and set it with a compatible blind-rivet tool.
- Inspect the completed joint. Do not rely on the closed-end body alone as proof of waterproofing or pressure sealing.
Customization may be available subject to quantity requirements and technical review. Contact us to discuss your specifications and confirm feasibility.
FAQ
Common Questions
What hole size should I use?
Use the recommended hole range for the selected rivet size. As a general guide, rivets under 4 mm in diameter typically use a hole from the nominal diameter up to 0.1 mm larger. Rivets 4 mm and larger typically use a hole from the nominal diameter up to 0.2 mm larger. Confirm the size-specific recommendation and fit before installation.
Are these rivets all copper?
No. The rivet body is copper and the mandrel is steel.
Are closed-end blind rivets waterproof?
The closed-end body helps limit passage through the center of the fastener, but the finished joint depends on hole size, fit, workpiece condition, installation quality, and the complete joint design. It should not be treated as an unconditional waterproof rating.
Can these rivets be installed from one side?
Yes. Blind rivets are installed from the accessible side with a compatible blind-rivet tool.
