When uncompromising strength and corrosion resistance are non-negotiable, select our #2 (3/8") self-piercing grommets made from premium 304 Stainless Steel. This marine-grade alloy offers outstanding durability, resisting rust and stains even in humid, challenging outdoor conditions. The high chromium content allows the material to "self-repair" against minor scratches, ensuring a clean, modern appearance with minimal maintenance. These heavy-gauge components are indispensable for demanding projects like boat covers, marine upholstery, industrial awnings, and other heavy-duty applications. The self-piercing design means the strong steel cuts through and sets with the washer in a single forceful action, providing a robust, long-term fastening solution.
