Structural Rivets

GO-Bulb High Strength Rivet

GO-Bulb high-strength structural rivets feature a mechanical mandrel locking mechanism that forms a large, load-distributing blind-side bulb during installation. This engineered bulbing action provides exceptional shear and tensile load capabilities while preventing deformation in thin or brittle sheet materials. The fastener exhibits superior vibration resistance and hole-filling properties, compensating for misaligned or oversized drilled holes. Industrial applications include heavy-duty automotive chassis assembly, HVAC ducting, and architectural panel cladding where permanent, one-sided installation is required.
