Fabric Grommets
Press these grommets 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 can be used outdoors.
Grommets with a tooth lock washer keep material from loosening and rotating better than those with a standard washer.
Grommets that meet NASM16491 and NASM20230 adhere to military dimensional standards.
Brass grommets are strong and have good corrosion resistance. Nickel-plated brass grommets have more corrosion resistance than brass grommets. Aluminum grommets are lightweight and have good corrosion resistance. Stainless steel grommets have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.
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).
