Aluminum Blind Rivet AB4-6A 5/16-3/8-in Grip

The Howmet / Marson BR4-6AAD (M40221) AB4-6A aluminum blind rivet is an open-end, all-aluminum rivet with a 1/8-inch (0.125 in) nominal diameter and a grip range of 0.313-0.375 inches (~5⁄16- to 3⁄8-inch / ~7.95-9.52 mm). It features a dome (button) head, aluminum mandrel, plain uncoated finish, and is designed for securing relatively thick material assemblies from one side. Made in Mexico, this rivet delivers corrosion resistance, lightweight strength, and longer grip capacity than smaller AB4-Series rivets.
