The extended neck on the washer of these grommets adds reinforcement so you can use them in thicker material such as woven fabrics. Press them into a hole you've already cut. 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. Use a cutting punch (sold separately) to create the hole, then set the grommet using either an installation punch or a press (both sold separately). Grommet trade size refers to the hole size and the size of the installation tool needed. All of these grommets adhere to military dimensional standards MIL-G-16491, NASM20230, and AN230. They can be used outdoors.

Brass grommets are strong and have good corrosion resistance. Nickel-plated brass grommets have more corrosion resistance than brass grommets.

Hammer-driven cutting punches create holes for installing grommets when you strike them with a wooden or rawhide mallet. Hammer-driven installation punches set grommets in a hole when you strike them with a wooden or rawhide mallet. Manual presses set grommets in a hole when you squeeze the adjustable pliers-grip handle. Requires a die set (sold separately).
