DEDRA 11Y501 rivet

Set of 50 aluminium blind rivets by Dedra, size 4.8 × 8 mm. These rivets are intended for permanent mechanical fastening of thin metal sheets, plastic panels and other lightweight materials. Their blind (pop) design allows installation from one side, making them practical for repair, assembly and do-it-yourself projects in workshops, on vehicles and for household fittings. The aluminium construction provides a lightweight and corrosion-resistant connection suitable for indoor and sheltered outdoor use.

Advantages

Aluminium rivets offer a balance of light weight and resistance to corrosion, reducing the risk of galvanic reaction with similar metals in non-critical applications. The blind rivet format enables fast, repeatable installation using manual or pneumatic rivet guns without access to the back of the joined materials. Supplied as a pack of 50, these rivets are convenient for small to medium jobs and routine maintenance tasks.

Suitable for

• Joining thin aluminium or steel sheets
• Securing plastic panels and acrylics
• Automotive trim and bodywork repairs (non-structural)
• Furniture assembly and light metal framing
• General DIY, hobby and workshop tasks

Key specifications

• Material: aluminium body and mandrel
• Rivet type: blind (pop) rivet
• Diameter: 4.8 mm
• Grip length: suitable for 8 mm total thickness
• Pack quantity: 50 pieces
• Corrosion resistance: suitable for indoor and sheltered outdoor use

How to use

Drill a hole matching the rivet diameter, position the rivet through the aligned materials, and insert the mandrel into a compatible rivet gun. Squeeze the tool until the mandrel snaps off and the blind head forms, securing the materials. Check that the rivet head sits flush and that the clamp is firm; use the correct rivet size and tool nosepiece for reliable results. Dispose of spent mandrels according to local waste guidelines.

Usage recommendations

For best results, use these 4.8 × 8 mm aluminium rivets with a rivet gun rated for this diameter and with a matching nosepiece. Pre-drill clean holes, avoid overtightening which can deform thin sheets, and consider using seals or washers when joining dissimilar metals to reduce corrosion risk in exposed environments.
