Restagraf – Expanded Head Aluminum Rivet 4.8 × 20 mm

Blind rivet with a expanded head (large flange) made of aluminum for strong and clean assemblies in bodywork: ideal for mounting license plates, coverings, supports, and accessories on thin sheets.

Key Features

• Expanded head: large bearing surface that distributes the load and prevents tearing in thin supports.
• Aluminum: lightweight, rustproof, and aesthetic for a clean exterior finish.
• Permanent fastening: reliable clamping, resistant to vibrations and weather conditions.
• Workshop use: compatible with steel/aluminum sheets, rigid plastics (with appropriate drilling).

Technical Specifications

• Body diameter: 4.8 mm
• Length: 20 mm
• Head: expanded (large flange) for thin supports
• Body material: aluminum
• Mandrel (nail): steel (usually zinc-plated)
• Recommended drilling: Ø 4.9 to 5.1 mm (depending on support and tolerances)
• Indicative assembly range: ~5–12 mm (to be verified according to application)
• Field of use: license plates, trims, profiles, various supports

Installation Tips

1. Mark and drill at the recommended diameter. Deburr and degrease the edges.
2. Insert the rivet (head on the finish side), position the pliers on the mandrel.
3. Operate the pliers until the mandrel breaks; check the rear expansion and flushness.
4. For very thin plastics, add a washer on the rear side if necessary.

Best Practices & Safety

• Choose the length based on the total thickness to be assembled for proper setting.
• Use a rivet plier in good condition; wear PPE (glasses) during mandrel breakage.
• Avoid unfavorable galvanic contact (unprotected aluminum/steel) outdoors: protect/paint if necessary.
