The Hillman zinc plated, steel, wood screws are designed to tackle wood applications; these wood screws are used to join two pieces of wood. The smooth shank design allows the screw to pull two pieces of wood together for a reliable join/connection, while preventing the wood from pulling or splitting. The flat head design makes for a flush placement against the surface while the tapered threads make for a strong hold. The wood screws feature a zinc finish for some corrosion protection while the steel material offers durability.
