Micron Self-Piercing Grommets & Washers, #3 (7/16" ID), Brass Plated Iron, 500-Set Bulk Pack, Heavy Duty for Tarps, Banners, Vinyl & Fabric

MICRON self-piercing iron grommets with washers are heavy-duty grommet sets designed to pierce and set efficiently (with the correct setting die/tool) so you can reinforce holes without pre-punching, making them ideal for banners, tarps, vinyl, fabric, leather, and production work where speed and consistency matter; choose the size you need—#1 (5/16"), #2 (3/8"), #3 (7/16"), or #5 (5/8")—and select your preferred finish such as Antique Brass, Black, Brass, Nickel, or zinc-plated iron on select bulk options, then pick the quantity that fits your workflow (500 complete sets for standard packs or 10,000 count for high-volume runs), and install using the matching size setting die/tool for best results (tooling sold separately).

• SELF-PIERCING = NO PRE-PUNCHED HOLE: Designed to pierce and set in one operation with the correct setting die/tool, saving time on banners, tarps, vinyl, fabric, leather, and similar materials.
