Large Flange Head Rivets

What Are Large Flange Head Rivets?

Large Flange Head Rivets are a variety of pop rivets distinguished by their wider domed head, which flares out to create an extra-large bearing surface area compared to standard rivets. This large flange is the main feature that gives these rivets superior strength and grip for demanding connections.

The expanded domed head distributes force evenly across a larger contact area on the materials being joined. This prevents damage while providing excellent resistance against shear and tension stresses. The broad flange also reduces the risk of pull-through or material cracking compared to small head rivets.

Constructed similarly to other pop rivets, Large Flange Head Rivets consist of a tubular rivet body and central mandrel. During installation using a rivet gun or tool, the mandrel snaps off once the rivet reaches the set position, expanding the body to form a permanent fastening.

Typical Applications and Uses

• HVAC Ducting - The wide head attaches sheet metal firmly without tearing soft metal. 
• Siding/Wall Panels - Securely fastens aluminum, galvanized steel, and composite exterior wall coverings.
• Metal Fabrication - Joins steel, iron, or aluminum in high-stress welds and frames.
