Blind rivet with a expanded head (large flange) made of aluminum for strong and clean assemblies in bodywork. Ideal for attaching license plates, trims, and accessories on thin sheets or sensitive supports.

• Length: 25 mm
• Head: expanded (large flange)
• Body material: aluminum
• Mandrel (nail): steel (usually zinc-plated)
• Recommended drilling: Ø 4.9 to 5.1 mm (depending on support/tolerances)

• Fields of application: license plates, trims, profiles, various supports

Installation Tips

1. Mark and drill at the recommended diameter; deburr and degrease.
2. Insert the rivet (head on the finish side) then position the pliers on the mandrel.
3. Operate the pliers until the mandrel breaks; check the rear expansion and flushness.
4. On very thin plastics, add a distribution 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.
• Prevent unfavorable galvanic couples (aluminum/steel) outdoors: protect/paint if necessary.
