4305_REST - Large Head Aluminum Rivet 4.8 x 20mm RESTAGRAF

To improve

Aluminum rivet with large head 4.8 × 20 mm for sheet metal and soft material assemblies (plastics, composites, thin sheets) in bodywork, maintenance, and industry. The large head better distributes loads and limits tearing or marking, while allowing for quick and clean installation without rear access.

Dimensions: Body Ø 4.8 mm × length 20 mm
Type: POP rivet / blind aluminum rivet – large head

Advantages

• Large bearing surface: reduces the risk of tearing on thin/soft supports

• One-sided installation: ideal when the rear is inaccessible

• Quick and consistent installation with a manual, pneumatic, or battery-powered gun

• Lightweight due to the aluminum body

Characteristics

• Head: large (enlarged dome) for better distribution of forces

• Recommended drilling: Ø 5.0 mm (according to support tolerances)

• Grip / assembled thickness: ensure that 20 mm covers the required range

• Supports: steel, aluminum, plastics, composites (support washer recommended on very soft materials)

• Applications: coverings, facings, splash guards, fairings, light plates, and profiles

Usage tips

• Drill perpendicularly at Ø 5.0 mm, deburr and degrease before installation

• Use an appropriate riveting gun; check the correct formation of the head

• In humid environments, protect the drilled edges and consider a washer on very soft supports
