Bulb Type Rivets are high‑strength blind fasteners designed to provide exceptional grip and load distribution in thin or soft materials. When installed, the rivet body expands into a large bulb shape on the blind side, delivering superior clamp force and resistance to pull‑through. Ideal for applications where access is limited to one side, bulb type rivets are commonly used in sheet metal, plastics, composites and light structural assemblies across manufacturing, fabrication and maintenance environments.
