PolyBulb® blind rivets
PolyBulb® blind rivets have a large disc-shaped bulb formation. This practical head shape evenly distributes the contact pressure over the component, making it the perfect fastener for riveting both soft and brittle components such as plastics and composite materials. A PolyBulb® blind rivet replaces up to three conventional blind rivets.
