4.0mm x 14mm Flange = 12mm Large Flange Blind Rivets – Aluminium Body / Steel Mandrel (Pop Rivets)

Large Flange Blind Rivets – Aluminium Body / Steel Mandrel (Pop Rivets)

These break-stem blind rivets combine a lightweight aluminium sleeve with a high-strength steel mandrel for a secure and permanent joint. The enlarged head offers twice the under-head bearing surface of a standard dome head rivet, so it distributes clamping load over a larger area and reduces the risk of tearing in thin or soft materials. Because a blind rivet only needs access to one side of the joint, installation is quick and straightforward using a hand or pneumatic riveter. Once set, the mandrel snaps off flush, leaving a clean finish that resists loosening even under vibration.

Key Benefits & Features

• Large flange head: Spreads the load and protects soft or brittle materials from pull-through.
• Recommended for thin sheets: Ideal for situations where small holes need to be covered; perfect for assembling soft materials to a rigid substrate.
• Aluminium body with steel mandrel: Combines light weight and corrosion resistance with high tensile and shear strength.
• Blind installation: Requires access to only one side of the workpiece, making these rivets perfect for confined or hard-to-reach areas.
• Permanent, tamper-resistant joint: Resists vibration and does not require retightening.
• Versatile fastening: Suitable for joining metals, plastics, and composite panels.

Typical Uses

• Fixing thin sheet metal to rigid frames in automotive bodywork and HVAC ducting.
• Mounting brackets and fittings on soft plastics, fibreglass or plywood.
• Repairing or assembling enclosures, panels and casings where the back is inaccessible.
• DIY, marine and electronics projects requiring a strong, flush joint.

Summary

Large-flange blind rivets provide a reliable, vibration-resistant fastening solution for thin or delicate materials. Their wide head spreads the load, while the blind installation method simplifies assembly and saves time. Use them whenever you need a fast, clean and durable joint in sheet metal, plastics or composites.
