A 50% larger head diameter than standard domed head blind rivets distributes pressure where the head meets the material surface. Use for covering irregular holes as well as extra holding power when fastening soft, thin materials to a rigid backing. The mandrel expands the rivet body to completely fill the hole, providing the highest shear and tensile strengths of all the blind rivets we offer. The portion of the mandrel that's retained inside the rivet after installation won't loosen over time and fall out. Made of aluminum, rivets are lightweight, nonmagnetic, and resist mild corrosion. They join material when you only have access to one side. A low-profile domed head creates a finished appearance.

The combined thickness of material must fall within the rivet's material thickness range. Shear strength is the amount of force it takes to break a rivet from the side, and tensile strength is the amount of pull a rivet can withstand without breaking. Joint strength is also affected by rivet spacing and hole size.

A blind rivet tool (sold separately) with a nosepiece that matches the rivet's diameter is required for installation.
