1/8 x 1/2 blind rivet is a common type of pop rivet with a 1/8-inch (3.2mm) diameter and a 1/2-inch (12.7mm) grip length, used for connecting two or more materials from one side only. They are typically made from aluminum grip and steel mandrel, offering corrosion resistance and strength for both indoor and outdoor use. These versatile fasteners are ideal for light-duty applications like metal, wood, and plastic, providing a secure, reliable connection for projects such as attaching insulation panels, HVAC components, or gutters.
