Self-Drilling vs. Self-Tapping Screws: What’s the Difference?

Self-drilling and self-tapping screws are two of the most popular types of fasteners used today. However, while similar in name and function, they have numerous different qualities, making it essential to know the differences between them. In simple terms:

• Self-drilling screws feature built-in drill tips that allow them to drill their own hole.
• Self-tapping screws require pre-drilled holes for installation.

But there’s more to it than that! Choosing the right screws is important for several reasons: avoiding damage, saving on installation time, ensuring project longevity, to name a few. Keep reading to learn more about the differences between self-drilling and self-tapping screws, as well as common applications, materials, and other critical considerations.

What are Self-Drilling Screws?

Self-drilling screws are equipped with built-in drill tips that eliminate the need for pre-drilled holes. These fasteners create their own threads when installed, allowing for both drilling and fastening to occur simultaneously. While self-drilling screws can be used for a variety of projects, they are best used for working on metal-to-metal applications, including:

• HVAC applications
• Cladding
• Metal roofing
• Steel framing
• General construction tasks

What are Self-Tapping Screws?

On the other hand, self-tapping screws require pre-drilled holes for installation. As they’re installed, they cut their own threads into the pilot hole to form secure connections. Because they lack built-in drill tips, these fasteners are better suited for use with softer materials, such as:

• Aluminum
• Wood and plywood
• Plastics
• Fiberglass
• Polycarbonates
