Stainless Steel Blind Rivet MR40417 .188-.250 Grip

The Howmet MR40417 (your BR4-4STD) is a stainless steel (body and mandrel) blind rivet with a nominal diameter of 1/8-inch and a grip range of 3⁄16-inch to 1⁄4-inch (0.188-0.250 in). It is made for blind-side fastening where access is only possible from one side, offering high corrosion resistance and strong fastener performance. Supplied in bulk (often 500-pack), this rivet is especially useful for harsh or wet environments, steel assemblies, or exterior work where durability and longevity are required.
