Rivet Mandrel

Description

A rivet mandrel is an essential component of blind rivets, facilitating the secure fastening of materials in various industries. Typically featuring a cylindrical shape with a head on one end and a grip on the other, the mandrel is inserted into the rivet body during installation. When a rivet gun or similar tool pulls on the grip end, the mandrel deforms and breaks off at the head, expanding the blind rivet and creating a tight connection between the joined materials. Variations in mandrel design, such as grooves or serrations, help improve grip and prevent slipping during installation, while threaded or knurled surfaces enhance engagement with the rivet gun. Overall, rivet mandrels play a crucial role in efficient and reliable fastening processes across automotive, aerospace, construction, and manufacturing applications.
