The Bulbex® rivet is an aluminum alloy, non-structural breakstem rivet with a split tail formation where the rivet body collapses into three legs or petals. This unique collapse pattern provides a multi-grip grip range and a larger than normal blind side footprint. Multi-grip means the rivet has the capability to join component parts having a broad range of thicknesses, thus reducing inventory where a variety of rivet sizes might otherwise be necessary. The large blind side footprint is often referred to as a large secondary head and creates a load bearing surface which absorbs the force of setting the rivet. Otherwise the setting force, or clamp load, could accumulate in the application material and might damage the material. The design and fashion in which the rivet body collapses prevents any radial expansion of the rivet into the application hole - another safeguard against damage to the application material. The combination of large blind side bearing surface and lack of radial expansion makes Bulbex® ideal when application materials are so soft or brittle that the tensile force exerted by a conventional rivet would cause damage. This typically includes thin sheet, soft, brittle and low strength materials.
- Split tail formation provides a very large blind side bearing area against the rear shee
- Spreads the tail bearing load/clamp load on the rear sheet providing high resistance to pull-out loads
- Multi-grip capability accommodates wide variations in material thickness
- Retained stem avoids damage, electrical problems or rattling caused by loose stems
- Ideal for use in thin sheet materials
- Provides strong, vibration resistant joints
- No damage, electrical problems or rattling due to loose stems
