They are specifically engineered for optimal pliability and incredible strength in any environmental condition. Perfect for securing items such as heavy canvas bags, garment closures, or commercial shower curtains, these 1/2-inch components ensure a robust, long-lasting fastening. The self-piercing capability enables rapid deployment: you simply cut and fasten the heavy-gauge eyelets and the gripping washer in a single action, streamlining your process while maintaining industrial-grade longevity.
