What is a self-piercing grommet?
With self-piercing grommets, there is no need to pre-punch holes in the material before applying grommets! Our self-piercing grommets and dies combine two steps into one. Using one of our applicating machines, a die set and grommet works together allowing the grommet to cut its own hole in the material and close around the washer. This makes for fast and durable application. In addition, self-piercing grommets are a heavier gauge than traditional sheet metal grommets.
