Rust‑resistant grommets sized 14 × 8.4 mm (9/16 × 5/16) for heavyweight fabrics and outdoor applications. Each set includes a grommet and matching washer to reinforce the opening and distribute stress. Install on tarps, bags, covers and craft projects to add a neat, durable eyelet for cord or hooks. For best results, pre‑mark, cut the hole cleanly, and set on a firm surface using the appropriate hand tools.
