Large-Flange Steel Blind Rivet 1/8-In Grip Range

The Howmet MR40119 (your BR4-4SSDL code) is a large-flange steel blind rivet, steel body and mandrel, with a nominal 1/8-inch diameter. Designed for medium grip ranges, it features an expanded flange head to increase bearing surface, especially useful in soft or brittle materials or when hole sizes are oversized. Offered in bulk pack quantities, the MR40119 is ideal for heavy-duty steel fastening where both strength and surface protection are required.
