• High corrosion resistant coating
• Equivalent to service life of LYSAGHT® profile
• Provides 4-6 times more life than conventional galvanized fasteners
• Unique shank protection system minimizes damage to the protective coating on the screw
• Grip sheeting towards the seal to maximize water-proof ability
• Strong self tapping drill point and durable washer
