The advantages of self-tapping phillips head screws:
1.They are self-tapping which means there is no need to drill a pilot hole in either wood or metal.
2.Commonly have a sharp point that helps penetrate the material.
3.Self-tapping screws create a stronger and more secure fastening than regular screws because they create their own threads in the material,which helps to prevent the screw from coming loose over time.
