Aluminum Open-End Large Flange Dome Head Blind Rivets

Aluminum Open-End Large Flange Dome Head Blind Rivets

Product Overview

JUXIN FASTENERS supplies aluminum open-end blind rivets featuring a large flange dome head for applications requiring a wider bearing surface on the accessible side of the joint.

Compared with a standard dome head of the same nominal rivet diameter, a large flange design provides a wider contact area, helping distribute bearing loads over the joined material.

These blind rivets are suitable for one-sided installation in compatible sheet-metal, equipment panel, enclosure and other industrial assemblies.

Material and Part Number Configurations

Important: Option 2 is retained exactly as identified in the existing product information. 

Its body and mandrel materials require confirmation against the original PDF/CAD specification before publication of additional material claims.

Product Features

• Rivet Type: Open-End Blind Rivet

• Head Style: Large Flange Dome Head

• Body Material: 5052 Aluminum Alloy for the confirmed Option 1

• Installation: One-sided blind riveting

• Head Design: Enlarged bearing surface

• Application: Thin sheets, relatively soft materials and compatible panel assemblies

• Customization: Customer-specific dimensions and material configurations subject to technical review

Large Flange Head Design

The large flange head is the defining feature of this product.

Unlike a standard dome head, the enlarged flange provides a greater contact area against the accessible panel surface.

This can help:

• Distribute bearing loads over a larger area

• Reduce localized pressure on suitable thin or soft materials

• Improve head-side support in compatible assemblies

• Cover certain enlarged or irregular mounting holes where sufficient bearing area and proper rivet engagement remain available

A large flange does not automatically increase the rivet's rated shear or tensile strength.

Joint performance depends on the complete rivet configuration, material combination, hole dimensions, grip range and loading conditions.

Dimensions and Technical Specifications

Technical drawings and dimensional data: Refer to the existing PDF/CAD documentation, pages 91–92.

All original dimensions, tolerances, part numbers and technical drawings remain subject to the approved product documentation.

Grip Range and Panel Thickness

Grip range is the total thickness of the materials that the blind rivet is designed to fasten.

The selected rivet must accommodate the actual material stack-up.

Important engineering considerations include:

• Total joined material thickness

• Panel material and stiffness

• Mounting-hole diameter

• Rivet body diameter

• Rivet body length

• Large flange head diameter

• Blind-side clearance

• Required joint performance

Rivet body length and grip range are not interchangeable dimensions.

For thin or relatively soft panels, both the head-side bearing surface and blind-side deformation must be evaluated.

Metric and Inch Diameter Reference

The following values are general nominal diameter references used in blind riveting.

These values are dimensional references only. They do not confirm the available sizes of this particular product.

Actual metric and inch-designated rivets must be checked for dimensional tolerances, hole requirements, grip range and mechanical compatibility before substitution.

Installation Method

Large flange open-end blind rivets are installed using a compatible blind riveting tool and nosepiece.

During installation, the tool pulls the mandrel while the flange remains seated against the accessible panel.

The rivet body deforms on the blind side to form the retaining connection, and the mandrel breaks at its designed break point.

For reliable assembly, the selected rivet must match the specified hole size, material thickness and installation tooling.

The enlarged flange must seat correctly against the panel surface without unintended interference.

Typical Industrial Applications

Large flange aluminum blind rivets may be used in compatible applications involving:

• Thin sheet-metal panels

• Equipment housings and enclosures

• Electrical cabinets and panels

• HVAC equipment panels

• Industrial machinery covers

• Metal-to-polymer assemblies

• Decorative or finished panel assemblies

• General OEM sheet-metal fabrication

Application suitability depends on the actual joint geometry, material stack-up and required performance.

Material and Corrosion Considerations

The confirmed aluminum-body configuration uses 5052 aluminum alloy.

The complete rivet assembly includes both the body and mandrel, and the mandrel material can affect the joint's setting characteristics and environmental considerations.

Where different metals are combined, corrosion behavior depends on the materials, surface finishes, moisture exposure and mating components.

Specific corrosion-resistance or mechanical-performance values should be established from the applicable product specification and verified test data.

Inspection and Quality Requirements

For customer-specific large flange blind rivets, relevant inspection characteristics may include:

• Rivet body diameter and length

• Large flange head diameter and height

• Mandrel dimensions

• Material identification

• Hole and grip-range compatibility

• Surface condition

• Setting characteristics

• Shear and tensile performance where specified

The actual inspection scope and acceptance criteria depend on the approved drawing and customer requirements.

OEM Customization and Bulk Supply

JUXIN FASTENERS supports drawing-based OEM sourcing for large flange blind rivets.

Custom requirements may involve body dimensions, flange geometry, mandrel material, surface finish, packaging and other application-specific characteristics.

Manufacturing feasibility and product availability are reviewed against the required technical specifications and purchasing quantities.

Frequently Asked Questions

What is a large flange blind rivet?

A large flange blind rivet has an enlarged head that provides a wider bearing surface against the accessible side of the joined material.

What is the difference between a large flange and a standard dome head rivet?

A large flange head has a larger bearing diameter for a given rivet body size. The exact difference depends on the product dimensions.

Are large flange blind rivets suitable for thin materials?

They can be suitable for thin or relatively soft materials because the wider flange helps distribute bearing loads. 

The complete joint must still be evaluated for grip range and retention.

Can large flange blind rivets be installed from one side?

Yes. These open-end blind rivets use a one-sided installation process with a compatible riveting tool.

Do large flange rivets have higher shear strength?

Not necessarily. The larger head changes the bearing interface, but the rivet's shear performance depends on its body, material and design.

Can JUXIN supply custom large flange blind rivets?

JUXIN FASTENERS accepts customer-specific drawings and technical requirements for review and quotation.
