Structural screws significantly outperform universal screws and standard wood screws in their characteristics. The purpose of structural screws is for working with all types and grades of wood. The uniqueness of structural screws lies not only in their visual geometric differences but also in their mechanical properties. The ability to undergo maximum deformation during bending without fracture is due to the ideal balance of strength and plasticity of the steel.
