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

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 materials can Yellow Painted Trifold Blind Rivets be used on?

Due to their gentle and dispersed clamping force, these rivets are ideal for fastening thin, soft, and fragile materials such as metal sheets, plastic, PVC, wood, and composite panels without causing cracking or deformation.

What are the main advantages of a trifold expansion design?

The trifold mechanism expands into three wide, uniform lobes on the blind side. This creates a large clamping area that provides superior pull-out resistance, balanced holding force, and excellent vibration resistance.

Why choose a yellow painted finish for blind rivets?

The full-body yellow coating offers strong adhesion that resists peeling, fading, and corrosion in both indoor and outdoor environments, while providing visual identification and a decorative finish.

Can these rivets be installed from one side only?

Yes, as blind rivets, they require access to only one side of the assembly, making them perfect for enclosed structural components, tubing, or hard-to-reach installation points.

What packaging options and delivery lead times are available?

We offer bulk cartons (20-25kg), small color boxes, polybags, or custom assortment boxes. Stock items ship in 2-5 days, while custom container orders take approximately 15-20 working days.
