Standoff is mainly a type of fastener applied to sheet metal, thin plates, chassis, and cabinets. One end of Standoff's appearance is hexagonal, and the other end is cylindrical. There is a cutting groove between the hexagonal edge and the cylindrical shape, and its internal shape is internal thread. The hexagonal head is pressed into the preset hole of the thin plate by a press machine (the diameter of the preset hole is generally slightly smaller than the outer diameter of Standoff's cylinder), causing plastic deformation around the hole, and the deformed part is squeezed into the cutting groove of Standoff, Rivet Standoff tightly onto the thin plate to form an effectively fixed internal thread.
