Rivet, Racing Rivet Brand, Tri-Fold (Load Spreading), Large Flange, Aluminum Rivet, Aluminum Mandrel

Tri folding rivets have three legs that split behind the workpiece to secure the rivet in place. Large-flange head types have the largest bearing surface of blind rivets. They are used in oversized holes and to fasten soft or brittle materials to prevent pull-through. Aluminum has a high strength-to-weight ratio and is wear resistant, nonmagnetic and conductive. It is easier to form and machine than steel and is naturally noncorrosive.
