Learn about self-drilling screws, their types, applications, and why Horizon Inc supplies only high-quality, reliable screws for industrial and sheet metal assemblies.
A Complete Guide to Self-Drilling Screws: Types, Applications & Benefits
Fasteners are the foundation of every assembly, and among them, self-drilling screws have become essential for modern fabrication, sheet metal, and construction industries. These screws simplify installations by eliminating the need for pre-drilling — saving time, labor, and equipment.
At Horizon Inc, we supply high-quality, application-specific self-drilling screws sourced from trusted brands to ensure reliability, strength, and long-term performance.
Let’s explore what makes these screws so indispensable, and how to select the right one for your application.
📌 What Are Self-Drilling Screws?
A self-drilling screw combines a drill bit and a threaded screw into one fastener. The tip of the screw is designed to drill its own hole into metal or other materials, eliminating the need for a separate pilot hole.
Key Advantages:
- Faster assembly
- Reduced tool changes
- Clean, accurate drilling and fastening in one step
- Available in various coatings for corrosion resistance
