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 heavy-duty outdoor canvas. The integrated gripping washers securely lock the eyelets into place, maximizing material grip on items such as 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.
