1/8 x 1/4 blind rivet is a fastener with a 1/8-inch (3.2mm) body diameter and a 1/4-inch (6mm) grip length, designed to join two or more pieces of material from one side without needing access to the backside of the joint. These aluminum blind rivets, also known as pop rivets, are used in applications like light-duty metal, plastic, or leatherwork, where a secure, corrosion-resistant, and clean connection is needed.
