Description
The aluminum/steel mandrel version of the Howmet Marson 3⁄16-inch blind rivet (code “AB6-10ASD” / your “BR6-10ASD”) would combine an aluminum body with a steel mandrel, allowing a nominal 0.187-inch diameter with a grip range around 0.500- to 0.625-inch (~12.70-15.88 mm). It would use a dome/button head, plain finish, and be designed for blind-side fastening where added mandrel strength is needed but weight and corrosion considerations favor aluminum in the body. Best used where only one side of the assembly is accessible, and additional mandrel strength helps with shear/tensile load.
