DEDRA 11Y405 rivet

Aluminium blind rivets Dedra 4.0×16 mm, pack of 50 pieces are designed for permanent fastening of thin sheets and lightweight materials where access to the back side is restricted. These rivets feature an aluminium body and mandrel suitable for general repair and assembly tasks in metal and plastic panels, HVAC systems, automotive trim and similar applications. The corrosion-resistant aluminium construction makes them appropriate for both indoor and outdoor use, while the 4.0×16 mm size balances shear strength and minimal protrusion for neat finishes.

Advantages

These Dedra aluminium blind rivets provide a reliable, low-corrosion fastening solution that is easy to install with standard rivet guns. The consistent grip and deformation behavior ensure uniform joints across repeated use, while the compact size reduces visible heads and avoids excessive material spread. Supplied in a pack of 50, the set is convenient for small to medium projects and maintenance tasks, offering predictable performance when joining thin sheets and lightweight substrates.

Suitable for

• Joining thin metal sheets and aluminium panels
• Fastening plastic trim and lightweight components
• HVAC ductwork assembly and repairs
• Automotive interior and exterior trim fastening
• General workshop maintenance and small-scale fabrication

Key specifications

• Material: aluminium body and mandrel
• Nominal diameter: 4.0 mm
• Grip length / total length: 16 mm
• Pack quantity: 50 pieces
• Corrosion resistance: suitable for indoor and outdoor environments

How to use

Drill a hole of appropriate diameter through the materials to be joined, insert the rivet through the aligned parts so the head sits flush on the visible face, and position the mandrel into a compatible hand or pneumatic rivet gun. Actuate the tool until the mandrel breaks off and the blind end forms a secure bulbed joint. Inspect the final assembly for tightness and even clamping. For repeatable results, use a rivet gun with consistent pulling force matched to the 4.0 mm diameter.

Usage recommendations

For corrosion-sensitive or high-strength applications consider using alternative rivet materials or coatings; ensure hole size and grip range match the combined thickness of the joined materials. When working on painted or coated parts, protect surrounding surfaces and avoid overtightening to prevent deformation.
