Steel Blind Rivet MR40112 – 1/8-inch Grip Steel

The Howmet / Marson BR4-2SSD (equivalent to M40112 / MR40112) is an all-steel body and mandrel blind rivet with a nominal diameter of 1/8-inch designed for fastening when only one side is accessible. It has a grip range spanning 1⁄16-inch to 1⁄8-inch (i.e. for material thickness in that range). Because of its steel construction, it offers superior strength and durability compared to aluminum rivets, making it ideal for structural, heavy-duty, or load-bearing applications where corrosion can be managed or protected.
