Type 17 screws are a specific type of wood screw that are designed for use with softwood materials, such as pine or cedar. These screws are named after the Type 17 auger point, which is a specific type of sharp, pointed tip that allows the screw to easily penetrate and thread through the wood.

Type 17 screws have a unique design that includes a specially designed flute or groove just below the screw's head. This flute is designed to remove excess material as the screw is driven into the wood, which reduces the amount of splitting that can occur. This design feature makes them an ideal choice for attaching thin or soft wood without causing damage or splitting.

Type 17 screws are available in a variety of sizes and lengths, and they typically have a flat or countersunk head that can be easily driven flush with the surface of the wood. They can be used in a wide range of woodworking applications, including deck building, framing, and other outdoor construction projects where softwood is being used. They are also commonly used in cabinetry, furniture, and other indoor woodworking projects.
