5/32 x 1/2 blind rivet is a fastener with a 5/32-inch (approximately 4mm) diameter and a 1/2-inch (approximately 12.7mm) length, designed to join materials from one side only. It consists of an aluminum or steel body with a steel mandrel, providing a strong, corrosion-resistant connection for various applications in metal, wood, and plastic. These "pop rivets" are ideal for projects where access to the back of the material is limited, such as in automotive repair or home improvement, and are installed with a standard rivet gun.
