RBA BulbLock Watertight Folding Rivets
- Watertight blind rivets engineered to help seal panels and joints against water intrusion—ideal for outdoor, washdown, and exposed assemblies.
- Folding / multi-leg backside expansion creates a wide bulb on the blind side for stronger pull-through resistance in thin sheet metal, plastics, and composites.
- One-side (blind) installation for fast production when you can’t access the backside—great for enclosures, tubes, and closed sections.
- Large bearing surface spreads load to reduce cracking, distortion, and stress concentration in fragile or thin materials.
- Designed for dependable watertight sheet metal fastening in applications that see vibration and movement.
