Use: You will use the grommet mainly in the field of textile production (when sewing jackets, sweatshirts, etc.). Riveting is done manually or with a press.
Inner diameter of the washer: 8 mm
Outer diameter of the washer: 13 mm
For the riveting is suitable only the die mold and press that is listed in the description. With any different type they can not be properly attached.
Punches with a smaller diameter than the grommet should be used for elastic fabrics. For solids, the diameter of the puncher should be the same as the diameter of the grommet.
