Self-Piercing Fabric Grommets
The sharp neck on these grommets cuts the material as you press them into place, eliminating the need for a cutting punch. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable through your material. To install, use a die set and bench-mount manual press (both sold separately). Grommets with grommet trade sizes 0, 1, and 2 require a die set adapter for installation. Grommet trade size refers to the grommet's hole size once set. Made of brass, all of these grommets are strong and have good corrosion resistance.
Grommets with a tooth lock washer, also known as a spur washer, have an elongated neck and teeth for extra reinforcement so you can use these grommets in thick materials such as canvas. They also have a rolled rim, which provides added grip.
