Aluminum Blind Rivet AB4-5A; .250-.375-inch Grip

The Howmet / Marson BR4-5AAD (M40220) is an all-aluminum AB4-5A blind rivet with a body and mandrel made of aluminum. It has a nominal diameter of 1/8-inch (0.125 in) and is designed to fasten materials with total thicknesses between 0.250-0.375 inches (~6.35-9.53 mm). Ideal for open-end fastening operations where access is only available from one side, this rivet delivers lightweight fasteners with good corrosion resistance, suitable for moderately thick panels or overlapping material assemblies.
