For which products requiring a seal is the closed-end rivet suitable?
Closed-end rivets are suitable for applications such as cabinets, enclosures, ductwork, vehicle panels, and outdoor equipment. They effectively prevent dust, moisture, rain, or air from entering the joints, thereby enhancing the overall reliability and service life of the product.
Can closed-end rivets completely prevent water leakage?
Closed-end rivets can effectively improve the sealing performance of joints, but the actual waterproofing effectiveness of your product also depends on hole diameter, tolerances, installation quality, and product design. For most industrial applications, they can significantly reduce the risk of water seepage.
How do I determine the specifications for the closed-end rivets I need?
When determining the specifications for a closed-end rivet, you need to consider three factors: hole diameter, total sheet thickness, and application. The hole diameter determines the rivet diameter, the total sheet thickness determines the clamping range, and the application determines the material and surface finish. If you are unsure how to choose, simply send us your drawings, photos of samples, hole diameter, sheet thickness, and industry of application, and we can recommend the appropriate closed-end rivet specifications for you.
Do you offer custom manufacturing for closed-end rivets?
Yes, we do. If you have specific application requirements, we can customize closed-end rivets based on your drawings, samples, or intended use. You can customize the dimensions, material, head type, surface finish, color, and packaging. For example, for outdoor equipment, you can choose a superior corrosion-resistant surface finish; for distribution and sales, you can also opt for OEM packaging. Simply provide us with the specifications, quantity, and application requirements, and we will develop a professional solution tailored to your needs.
Why Are More and More OEM Manufacturers Choosing Closed-End Rivets?
Because they not only provide a reliable connection but also help reduce issues such as air leaks, dust ingress, and moisture penetration, thereby lowering after-sales maintenance costs and improving overall product quality and customer satisfaction.

What are Closed-End Blind Rivets
Closed-end blind rivets are a type of blind rivet with a closed end.
Unlike open-end blind rivets, the end of the rivet body is closed rather than open. They are suitable for fastenings that require a sealed, protected joint.
The Core Structure of Closed-End Blind Rivets
Closed-end blind rivets consist primarily of two parts: the rivet body and the mandrel.
The rivet body is the component that primarily bears the load and undergoes forming; after installation, it deforms to clamp the sheet metal. The mandrel is used to drive the rivet body into deformation during riveting, thereby completing the riveting process.
How Closed-End Blind Rivets Work
Closed-End Blind Rivets create a secure connection by pulling the mandrel, causing the rivet body to expand and deform on the back side of the material, thereby clamping the sheets together.
Installation requires working from only one side of the workpiece. After inserting the rivet into a pre-drilled hole, use a rivet gun to pull the mandrel. The mandrel causes the tail end of the rivet body to deform, causing the body to expand on the back side of the sheet metal and generate clamping force. Once the riveting is complete, the mandrel breaks at a predetermined breaking point, ultimately forming a stable connection.
Closed End Blind Rivets vs Open End Blind Rivets

| Water Resistance | More suitable for waterproof requirements | Not suitable for high-sealing requirements |
| Dust Protection | Better dust protection | Weaker dust protection |
| Air Leakage Resistance | Better air leakage control | Basic air leakage control |
| Cost | Higher cost | Lower cost |
| Recommended Applications | Electrical cabinets, HVAC ducts, vehicle bodies, outdoor equipment | General sheet metal fastening |

Common Sizes and Selection Parameters
- Diameter
- Rivet Length
- Grip Range
- Hole Size
- Head Diameter
- Material
- Finish
- Tensile Strength

Grip Range
This refers to the total thickness range of materials that the rivet can effectively grip.
For example: The total thickness of two layers of sheet metal, when added together, is the total grip thickness that the customer needs to consider.
If the wrong Grip Range is selected, it may result in:
- Inadequate clamping
- Loosening after riveting
- Poor sealing
- Abnormal rivet head formation
- Riveting failure
- Insufficient strength
