Fastenere open end blind pop rivets deliver strong, reliable fastening for metal, sheet, furniture, marine, and kit assemblies. Open-end blind rivets are tubular with a mandrel through the center; the full assembly is inserted into a drilled hole and a tool pulls the mandrel, expanding the blind end and snapping it off for a secure hold. Made of durable low-carbon steel with a high-strength steel mandrel, they provide greater tensile and shear performance than aluminum rivets. This 4-2 size rivet measures 1/8" x 1/8" with a countersunk head, .233" head diameter, .031" head height, and requires a #30 drill bit. Grip range is 5/64" to 1/8". Meeting IFI-126 standards, these rivets offer dependable performance for stainless steel, aluminum, washers, nuts, and long-lasting fabrication projects.
