7.5 Aluminum Bulbtight Trifirm Rivet

Installation Sequence

The “cracked” tail molding disperses the mandrel pressure bearing load / riveting load on rear plate.
The mandrel pressure bearing load / riveting load are dispersed on rear plate, which provides the high mandrel retaining force.
The retained mandrel can avoid damage, electric leakage or marowak sound and other problems caused by falling off of the mandrel.
Multi-grip property adaptable to the scope of width of sheet material thickness.
As an ideal selection for sheet materials, it can provide high mandrel retaining force.
