Description
The Marson BR4-4AADL (M40219) is a large-flange aluminum blind rivet in the AB4-4A series. It has a 1/8-inch (0.125 in / ~3.18 mm) nominal body diameter and accommodates material grip thickness between 0.188-0.250 inches (≈ 4.78-6.35 mm). With both body and mandrel made of aluminum (all-aluminum construction) and a plain, uncoated finish, it provides lightweight corrosion resistance. The large flange (oversized head) offers increased bearing surface, reducing pull-through and distributing load over softer or more delicate materials. Ideal for medium-thickness assemblies where access is only from one side.
