Countersunk wing screws made from carbon steel are specially designed for fastening various materials, such as wood mansards, plywood, and floor sheets, … to steel substrates. The flat head design allows the screw to sit flush with the surface of the wood, providing a clean and finished appearance. This feature is especially important in applications where aesthetics matter. The winged design helps in reaming a hole in wood, allowing for better penetration and stability when fastening. The wings create a larger hole, which reduces the potential for splitting the wood and ensures a secure fit. Their unique design and features make them an optimal choice for construction and woodworking applications.
