50-Pack Tri-Fold Blind Rivets – Aluminum Alloy | 3.2mm, 4.0mm & 4.8mm
Get a rock-solid, rust-resistant fastening solution with these tri-fold (triple-leg) blind rivets. Made from high-quality aluminum alloy, this 50-piece set covers three of the most common rivet diameters — 3.2mm, 4.0mm, and 4.8mm — making them ideal for a wide range of DIY, automotive, plumbing, and furniture projects. Made in Mainland China.
Why Choose Tri-Fold Blind Rivets?
- Triple-Leg Expansion Design: Unlike standard blind rivets, the three-prong folding action spreads clamping force over a much larger surface area — perfect for oversized, irregular, or soft-material holes.
- High-Quality Aluminum Alloy: Naturally rust-resistant and lightweight, these rivets maintain their integrity in both indoor and outdoor environments without corroding over time.
- Workpiece Protection: The moderate hardness of the aluminum and the controlled folding action mean softer or more fragile materials — rubber, plastic, thin sheet goods — are fastened securely without cracking or crushing.
- Versatile Sizing: Three diameters in one package (3.2mm, 4.0mm, 4.8mm) so you always have the right size on hand for the job.
- Wide Application Range: Suitable for automotive exhaust systems, furniture assembly, plumbing fixtures, instruments, DIY crafts, and general home improvement tasks.

Frequently Asked Questions
Q: What sizes of blind rivets are included in this 50-piece pack?
A: This pack includes tri-fold blind rivets in three diameters: 3.2mm, 4.0mm, and 4.8mm. Having all three sizes in one package ensures you're prepared for a variety of fastening applications without needing multiple orders.
Q: What materials can these tri-fold aluminum blind rivets be used on?
A: These rivets are engineered to work on a wide range of materials including rubber, plastic, thin sheet metal, wood panels, and other soft or fragile substrates. The three-leg folding action distributes clamping load gently and evenly, making them a great choice where standard rivets might cause damage.
Q: Are these rivets suitable for outdoor use?
A: Yes! The aluminum alloy construction makes these rivets naturally resistant to rust and corrosion, so they perform reliably in both indoor and outdoor environments — from automotive exhaust systems to outdoor furniture assembly.
Q: Do I need a special rivet gun for tri-fold blind rivets?
A: These rivets are compatible with standard hand or pneumatic rivet guns that accept the corresponding mandrel diameter. Always check that your rivet gun's nose piece matches the rivet diameter (3.2mm, 4.0mm, or 4.8mm) before use.
