The sharp tip and aggressive threads help penetrate dense wood, and the advanced coating ensures excellent corrosion resistance, making it an ideal choice for external freshwater buildings and pressure treated wood applications. It eliminates pre drilling requirements, shortens installation time by half, and improves construction efficiency. These screws feature slotted tips and specialized rolling handles, which can reduce splitting and greatly reduce the torque required during installation. They also provide strong shear values, making them ideal for fixing external deck frames, fences, stair stringers, landscape wood, etc. in wood to wood outdoor buildings.
