Need some solid, all-purpose rivets for a project? This pack of 60 aluminum pull rivets (also called blind rivets) from uxcell has you covered. They're silver-toned, made from lightweight but strong aluminum which also has good corrosion resistance. The key specs are: Rivet Diameter is 5mm (about 0.2 inches), and the Grip Length (the part that expands) is 13mm (about 0.51 inches). The mandrel (the pin you pull) is 2.6mm thick, and the flange head is about 9.8mm wide. They're the 'open end' type with a break-away mandrel. Super important note: You NEED a rivet tool (a rivet gun or riveter) to install these. You drill a hole, pop the rivet in, and use the tool to pull the mandrel, which squishes the back of the rivet to hold things together securely. They're super versatile and used for all kinds of stuff - metalworking, DIY projects, repairing furniture, gutters, on cars, or even in crafts. Good for indoor or outdoor use. A handy, affordable pack to have in your toolbox for quick fixes and builds.
