However, it's essential to note that while self-drilling screws excel in many scenarios, they may not be suitable for all. Materials with high hardness or thickness, for example, might require a pre-drilled hole or a different type of screw. Always consider the material, load-bearing requirements, and environmental factors when selecting the appropriate fastener.
