Rivet, Pop Brand, Dome Head, Aluminum Rivet, Aluminum Mandrel, Black

Pop rivets are manufactured with a two-piece construction design; the first is the rivet body or the shell and the other is the stem or mandrel. Both parts are pre-assembled and ready to use. Fastening is done by using a special tool to draw the mandrel which causes the body to deform and clamp the joint. Once the designed clamping force is reached, the mandrel snaps and is discarded. The steel mandrel is pulled into or against the rivet body, breaking at or near the junction of the mandrel shank and its upset end. The head of the body is slightly rounded and twice as wide as the body diameter. Dome head is the most commonly specified head style because of its low profile and neat, finished appearance. The steel mandrel gives this style rivet greater tensile and shear values than aluminum rivets with aluminum mandrels. They should be used when fastening materials with similar mechanical and physical properties.
