These specialized #3 (7/16") self-piercing brass grommets offer exceptional structural integrity for tough applications. They are constructed from superior, heavy-gauge brass (a durable alloy of 70% copper and 30% zinc), and feature the distinctive Military Black Oxidized finish. This finish provides a tough, non-reflective surface that actively resists corrosion, making it an excellent choice for industrial textiles, covert gear, and medium-duty outdoor canvas. Use in commercial tents, rugged tarps, and promotional banners. Installation is quick and professional—these components are self-piercing, meaning they cut and set in one smooth action, boosting your production rate and ensuring long-term performance outdoors.

Great for:

• Banners
• Tarps
• Flags
• Light Canvas Projects
• Bags
• Shoes
• Shower Curtains

A note about grommets: There are many types. Most marine applications require heavier rolled rim spur grommets. These grip the fabric, so they don’t turn in the fabric hole. They are also much heavier in construction since the metal edges are rolled under. The self-piercing style are lighter weight grommets without rolled edges. They are ideal for utility-type projects. Some have smooth washers while others have small gripper teeth. The teeth help to keep the grommet from rotating and damaging the surrounding fabric, much like the heavier spur grommets.

Grommet dies must be matched to the grommet type. They cannot be interchanged.
