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 Painted Finish

High-adhesion full-body painted 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

Construction & Building Engineering

Fastening of metal curtain walls, building exterior wall panels, metal roofing, gutter systems, window and door frames, and decorative keels. The colored 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 internal and external aesthetics.

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 while improving overall decorative effect.

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 environments 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

Q1: How do trifold blind rivets differ from standard blind rivets?

Trifold blind rivets expand into three distinct lobes on the blind side during installation. This creates a much larger clamping surface area, distributing force evenly to prevent cracking or deformation in soft, thin, or brittle materials.

Q2: What materials are suitable for fastening with these rivets?

They are suitable for connecting metal sheets, plastics, PVC, wood, composite panels, and other fragile or soft materials where high clamping force must be distributed evenly.

Q3: How effective is the painted surface coating against rust and corrosion?

The high-adhesion protective coating covers the entire body, providing strong resistance against peeling, fading, moisture, and weather erosion, making them suitable for both indoor and outdoor applications.

Q4: Can these rivets be installed from one side only?

Yes, trifold blind rivets are specially designed for single-side blind installation. They require access from only one side of the assembly, ideal for enclosed structures, tubing, and hard-to-reach locations.

Q5: What customized options are available for rivet specifications?

We offer custom options including special surface colors, specific body sizes, non-standard dimensions, and custom packaging solutions to fit specific industry requirements.

Q6: What tools are required to install these trifold blind rivets?

They can be installed using standard manual, pneumatic, or electric rivet guns compatible with standard blind rivet mandrels.
