Superbulb is a high shear and tensile strength structural rivet that supports a wide range of fastener thicknesses: from 1.5 mm to 15.5 mm depending on product size. Superbulb, during its application and closing, forms a large head that mechanically locks the stem inside the body thanks to the crimps on the tubular. Superbulb is ideal for watertight applications due to its effective sealing effect.
- Bulb open counterhead
- Water tightness between the body and mandrel
