Large-Flange Steel Blind Rivet 3⁄16-in Grip Range

The Howmet / Marson BR6-10SSDL (M40156) is a large-flange, all-steel (body & mandrel) blind rivet, sized at 3⁄16-inch (0.187 in / ~4.75 mm) diameter. Designed for use where a broader bearing surface is needed (large flange) to protect soft, thin, or brittle facing materials, while being strong under load. Its grip range is from approximately 0.500-inch to 0.625-inch (~½- to 5⁄8-inch) material thickness. Ideal for blind-side fastening where access is only on one side, and high shear/tensile strength is required. Plain steel finish is assumed, typical of Howmet’s steel series.
