Features

Stable Trifold Expansion Structure

Expands into three uniform lobes after installation to create a large, tight clamping surface. It delivers balanced holding force, excellent vibration resistance and anti-loosening performance, suitable for dynamic working conditions.

Durable Yellow Painted Finish

High-adhesion full-body yellow coating resists peeling, fading and corrosion. It provides reliable rust protection for indoor and outdoor use, while offering distinct visual identification and decorative effects.

Universal Material Compatibility

Gentle dispersed clamping force avoids cracking or deformation. Ideal for fastening thin, soft and fragile materials including metal sheets, plastic, PVC, wood and composite panels.

Single-Side Blind Installation

Supports one-sided riveting only, perfect for enclosed or hard-to-reach mounting positions where backside operation is unavailable, greatly improving construction flexibility.

Lightweight & Reliable Strength

Premium full-aluminum construction features low weight and stable tensile & shear strength, realizing lightweight assembly without compromising fastening firmness.

Applications

1. Automotive interior trim assembly

White aluminium trifold blind rivets (all aluminum body and mandrel). They expand into three legs after riveting, spread pressure evenly, prevent pulling‑through on car plastic dashboards and door panels.

2. Building interior decoration panel fixing

All‑aluminum lantern blind rivets for thin decorative sheets. The tri‑fold design forms a wide back support, great for interior cladding, light wall panels and ceiling decorative parts.

3. Lightweight caravan & RV panel fastening

White coated trifold blind rivets with full aluminum construction. Three‑way expansion protects fragile thin plates, widely used for RV inner lining and lightweight body trim installation.

4. Advertising light box & signage fabrication

Aluminium tri‑fold blind pop rivets suit brittle and hollow materials. After installation, three split feet distribute load stably, ideal for assembling thin aluminium sign boards and illuminated light boxes.

5. HVAC ventilation duct and cabinet assembly

Corrosion‑resistant all aluminum trifold blind rivets. Single‑side installation, three‑leg expansion avoids sheet damage, reliable fasteners for air ducts and thin metal electrical enclosures.

Installation Guide

1
Prepare Parts & Tools: Pick the right rivet size based on your material thickness and hole size. Get your standard rivet gun ready and clean up dirt, dust and burrs from the mounting surface for a tight fit.
2
Drill Clean Holes: Drill holes to the required standard size. Keep holes straight and smooth, then clear out all debris inside to avoid loose installation.
3
Insert Rivet in Place: Feed the rivet fully through the pre-drilled hole until the rivet head sits flat and tight against the material surface, with the mandrel fully exposed.
4
Rivet & Lock Firmly: Grip the mandrel straight with your rivet gun and pull steadily. The rivet body will expand into three lobes to grip and lock the materials tightly, and the mandrel will snap off automatically once finished.
5
Check Finished Work: Double-check the final result. Make sure the rivet is fixed firmly with a flat head, no shaking, no tilted installation and no damaged coating.

Frequently Asked Questions

What makes trifold blind rivets different from standard blind rivets?

Trifold rivets expand into three separate legs (lobes) on the backside rather than bulging straight out. This provides a significantly larger surface area to spread clamping force evenly, making them ideal for soft, brittle, or thin materials.

Can trifold blind rivets be installed when only one side is accessible?

Yes, they are designed specifically for single-side (blind) installation. You only need access to the front mounting surface to insert and lock the rivet using a standard rivet gun.

Which materials are best fastened with trifold blind rivets?

They are ideal for lightweight and fragile materials such as plastic dashboards, thin sheet metals, PVC, wood, composite panels, and hollow structures commonly found in RVs, lightboxes, and HVAC systems.

What sizes and custom color options are available?

Available standard diameters include 3.2mm (1/8"), 4.0mm (5/32"), 4.8mm (3/16"), and 6.4mm (1/4"). We also offer customized body colors and finishes to match specific application demands.

What tools are required to install these rivets?

A standard manual, pneumatic, or electric blind rivet gun fitted with the appropriate nosepiece diameter for the chosen rivet size is all that is needed for installation.
