Blind Nut Riveter, Blind Rivet Stud
What is a blind rivet? Also known as POP Rivets or simply POP Rivets, blind rivets are used for applications that have no access to the back (blind side). Two-piece rivets are used in their construction. One is the rivet body, shell or hat, and the other is the stem or mandrel. Both the mandrel and hat are already assembled and ready for use. Installing rivets is done by using a riveting device to draw the mandrel. This causes the body's shape to change and clamps down on the joint. The mandrel is then snapped when it reaches the clamping force. Blind rivets are material-independent, so they can be used with different materials in the same way.
A hole must be drilled in order to use blind rivets. The rivet will then be seated within the hole. Next, a tool will pull the mandrel against hat of rivet. The mandrel's back may have a bulge at the end, or it is connected to the rivet in a way that causes the edges of hat to expand towards the material. This expansion builds pressure and pushes the material to the surface. A design fault in the mandrel then reaches its maximum force and snaps. A properly installed rivet will be left. The rivet will always install correctly if it is the right diameter and grip range.
Common Blind Rivet Applications. POP Rivets are easy to use if properly installed. They can be used in RVs. Trailers. Aircrafts. Machinery. Jeans. Small Electronics. Structural Beams. Battleships. Submersibles. The mandrel should not be measured. The measured length will not be the hat length. The rivet's grip range will be 1.5 times the measured length (including the ball at its end).
