Steel Blind Rivet MR40117 – 1/8-In, .188-.250 Grip

The Howmet MR40117 (also your BR4-4SSD) is a steel body blind rivet with a 1/8-inch nominal diameter, designed to fasten moderately thick materials when access is limited to one side. It supports a grip range of 3/16-inch to 1/4-inch (.188-.250 in), offering strength and durability in harsh or load-bearing conditions. Manufactured by Howmet, this steel rivet is ideal for structural applications, heavy sheet metal work, and environments where aluminum would not provide sufficient performance.
