The installation of embossing nut



DSO extrusion stud installation schematic diagram

1. The diameter of the mounting holes must match with the product.
2. Does not allow for secondary processing, such as deburring.
3. According to the picture on the right shows, install fasteners through the hole and into the mold.
4. In the case of parallel to the upper die and lower die, exert certain extrusion, install the stud to the plate, after the installation, screw head plane and install board face flush.
5, it is suggested that using the pressure riveting machine installation
