Tri-Fold Blind Rivets
Tri-Fold Blind Rivets
Tri-Fold Blind Rivets are designed for applications requiring fastening across varying material thicknesses with a single rivet type. RivetFast offers a complete range of Tri-Fold Blind Rivets in multiple materials, sizes, and finishes, providing consistent performance in industrial and manufacturing assemblies.
This product belongs to our Blind Rivets range.
What Are Tri-Fold Blind Rivets?
Tri-Fold Blind Rivets are engineered for applications where standard blind rivets may fail in soft, brittle, or thin sheet materials. During installation, the rivet body splits into three sections on the blind side, distributing the load evenly and improving joint retention.
They are ideal for fastening plastic panels, composite sheets, aluminum, and other lightweight materials.
Key Advantages of Tri-Fold Blind Rivets
Three-fold expansion on the blind side for superior load distribution
Reduces the risk of pull-through and surface damage
Ideal for soft or low-strength materials
Provides consistent clamping force and reliable joints
Suitable for blind-hole applications where backside access is limited
Available Materials, Head Types & Surface Finishes
Materials
Aluminium Alloy、Stainless Steel 、Steel
Surface treatment
Zinc Plating、Anodizing、Natural/Plain Finish、Custom Coatings
Head Type

Customized sizes and colors are available according to customer drawings.
Specifications & Sizes Options for Tri-Fold Blind Rivets
Tri-Fold Blind Rivets come in a wide range of diameters and grip lengths to accommodate varying material thicknesses.
Installation Tools & Setting Process for Tri-Fold Blind Rivets
Tri-Fold Blind Rivets can be installed using standard manual, pneumatic, or electric blind rivet tools.
Insert rivet into the pre-drilled hole→Engage the mandrel with the setting tool→Pull the mandrel until the rivet body expands into three segments on the blind side→Inspect the blind side for proper expansion and secure fastening
Tri-Fold Blind Rivets vs Structural Blind Rivets
| Feature | Tri-Fold Blind Rivets | Structural Blind Rivets |
|---|---|---|
| Expansion Design | Splits into three legs for wide backside spread | Internal locking mechanism |
| Performance on Soft/Thin Materials | Excellent – minimizes damage and distributes load evenly | Not ideal for soft materials |
| Pull-Through Resistance | Very high (large backside footprint) | Very high |
| Strength Level (Shear & Tensile) | Moderate | Very high (for structural applications) |
Typical Applications for Tri-Fold Blind Rivets
Tri-Fold Blind Rivets are ideal for thin or soft materials and are widely used in:
- Plastic panels and composite sheets
- Appliance housings and electronic enclosures
- Automotive interior panels and trim
- Light-gauge aluminum assemblies
- HVAC ducting and sheet metal assemblies
For applications requiring increased bearing surface on the visible side, Large Flange Open-End Blind Rivets may be considered.

Q1:What makes Tri-Fold Blind Rivets different from standard blind rivets?
Tri-Fold Blind Rivets expand into three separate sections on the blind side, providing superior load distribution and preventing pull-through in thin or soft materials, which standard rivets cannot achieve.
Q2:Can Tri-Fold Blind Rivets be used with plastics and composite panels?
Yes. Their three-fold expansion design is ideal for soft and brittle materials, including plastics, fiberglass, and composite sheets.
Q3:Are Large Flange Open-End Blind Rivets an alternative?
In some applications, Large Flange Open-End Blind Rivets can be used for added front-side bearing surface. The choice depends on material type, thickness, and load requirements.
Q4:What materials are available for Tri-Fold Blind Rivets?
Common combinations include Aluminum/Steel, Aluminum/Stainless Steel, Steel/Steel, and Stainless Steel/Stainless Steel.
Q5:What installation tools are recommended?
Manual, pneumatic, or battery-powered blind rivet tools compatible with the rivet diameter and grip range are recommended for consistent installation.
