R-Bulb Blind Rivet (All steel)

Installation Sequence

High shearing strength and tensile strength which can provide the solid and vibration resistant connection.
Provide the large blind side bearing area to be close to rear plate.
The mandrel pressure bearing load/riveting load are dispersed on the blind side sheets which makes it to be ideally used in sheet materials.
Good hole filling which can provide supplementary riveting for the irregular and over tolerance hole, oval or malposition holes.
Mandrel locking mechanism which avoids damage, electric leakage or marowak sound caused by the loosening of mandrel.
