Tri Bulb Structural Rivet - Aluminium
Brands you know and trust - Aerobolt
An all aluminuim tri-fold weatherproof structural rivet.
A high performing self-plugging rivet that differs from other types due to its tri-star shape blind?side anchor and washer combo, providing a weatherproof joint with a large blind side bearing area for lightweight applications.
The Tri-Bulb spreads the clamping force through the anchor blades whilst providing excellent pull through resistance, making them an ideal choice for the fabrication of pantech & refrigerated trucks to join thin sheets of aluminum, steel or laminate honeycomb panels where there isn't access on both sides of the application. This rivet is renowned for it's extended material grip range, enabling a single rivet to cover a greater range of gauges including curved or uneven surfaces.
An all aluminuim tri-folding weather resistant structural rivet.
A high performing self plugging rivet that differs from other types due to its propeller shape blind–side anchor and washer combo, providing a weatherproof joint with a large blind side bearing area for lightweight applications.
The Tri-Bulb spreads the clamping force through the anchor blades whilst providing excellent pull through resistance, making them an ideal choice for numerous lightweight panel applications. This rivet is renowned for it's extended material grip range, enabling a single rivet to cover a greater range of gauges including curved or uneven surfaces.

How to Install Tri-Bulb Lab.
Tri Bulb rivets work in a similar way to a standard blind rivets, but they have a unique design that allows it to provide a secure and reliable fastening solution. Here's how they generally work:
-
Preparation: To install a Tri Bulb rivet, you'll need a rivet gun or a rivet tool. The rivet consists of a cylindrical body (the shank) with a mandrel (a thin rod) passing through its center.
-
Insertion: The rivet is inserted into a pre-drilled hole in the materials to be joined. The rivet's shank should be long enough to pass through both materials and leave a small amount of extra length on the opposite side.
-
Pulling the Mandrel: With the rivet in place, the rivet gun is used to pull the mandrel through the center of the shank. As the mandrel is pulled, it deforms the unexpanded end of the shank, creating a "bulb" on the blind side of the materials.
-
Expansion and Locking: The bulb created by the mandrel's deformation expands against the backside of the materials. This expansion creates a secure grip and holds the materials together firmly. The mandrel eventually snaps off once the required pressure is achieved, leaving the installed rivet in place.
-
Finishing: The excess mandrel is discarded, and the installation is complete.
Tri Bulb rivets are often used in applications where a high-strength, vibration-resistant, and watertight joint is required. They are commonly used in the automotive industry, construction, HVAC systems, and more.
