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.

Application Fields

Construction & Building Engineering

Fastening of metal curtain walls, building exterior wall panels, metal roofing, gutter systems, window and door frames, and decorative keels. The yellow paint matches diversified building decoration styles and adapts to outdoor wind and rain erosion environments.

HVAC & Ventilation System

Assembly of ventilation ducts, air supply plenums, fan shells, and HVAC equipment casings. The uniform clamping ensures the tightness of duct connections and avoids air leakage, with stable performance for long-term indoor and outdoor operation.

Electronic & Electrical Equipment

Fastening of server casings, electrical control boxes, circuit board fixing brackets, and household appliance shells. Lightweight design avoids equipment load increase, and neat installation ensures the internal and external aesthetics of electronic products.

Furniture & Decoration Manufacturing

Assembly of metal-wood composite furniture, plastic furniture, decorative metal strips, and exhibition display racks. It will not damage thin plate and wood materials, and the yellow color improves the overall decorative effect of furniture.

Automotive & Transportation Accessories

Fastening of automotive interior parts, body decorative plates, guardrail accessories, and non-load-bearing structural parts of transport vehicles. Vibration-resistant structure adapts to vehicle driving vibration environment to prevent loosening.

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 (FAQ)

What makes Trifold Blind Rivets different from standard blind rivets?
Trifold blind rivets split into three distinct lobes (petals) on the blind side during installation. This creates a much larger load-bearing surface area, preventing pull-through and evenly distributing clamp force, making them ideal for soft or fragile materials.
What materials are best suited for these trifold rivets?
Because of their gentle and wide clamping force, they are perfect for delicate materials such as thin sheet metal, plastics, PVC, composite panels, wood, and fiberglass without causing cracking or surface deformation.
Are custom sizes and colors available for bulk orders?
Yes, we support custom specifications and body coatings. Options include black, yellow, and other customized colors to match your specific application or branding requirements.
Do I need special tools to install trifold blind rivets?
No standard specialized gun is strictly required; standard pneumatic, electric, or manual blind rivet guns matching the diameter of the rivet mandrel can be used for smooth installation.
How well do these rivets handle vibration and outdoor weather?
The high-adhesion painted finish delivers exceptional resistance against corrosion and moisture. Additionally, the expanded trifold structure provides superior vibration resistance, preventing fastening failure under dynamic conditions.
