    Aluminum Blind Rivet AB5-4A | 5⁄32-in, .188-.250 Grip

    Part #: BR5-4AAD

    The Howmet / Marson BR5-4AAD (part number M40235, in the AB5-4A series) is an all-aluminum open-end blind rivet featuring a 5⁄32-inch diameter body and mandrel. It supports material thickness (grip) between 0.188-inch to 0.250-inch (~4.78-6.35 mm). With a dome (button) head, plain (uncoated) finish, and aluminum 5052 construction, this rivet delivers lightweight corrosion-resistant fastening for medium thickness assemblies where access is only from one side. Ideal for fabrications in aluminum or mixed materials where minimizing weight and avoiding galvanic corrosion are priorities.
