Key Features & Benefits at a Glance
- Eliminates pre-drilling with integrated No. 3 drill tip, saving significant labor time and cost in sheet metal and aluminum assembly.
- Superior corrosion resistance provided by 18-8 Stainless Steel material, ensuring long-term reliability in demanding environments.
- Exceptional holding power achieved through thread forming technology, which creates strong, secure threads in ductile materials without cutting.
- High-torque installation enabled by the square drive, reducing cam-out and allowing for efficient, secure fastening.
- Optimized for thin materials with a maximum drilling thickness of 0.175", making it ideal for standard sheet metal and aluminum applications.
- Full-length threading ensures consistent grip and clamping force along the entire 1-3/4" length for a more reliable connection.
- Standard pan head design offers a low-profile, rounded finish for a clean appearance and good bearing surface.
Professional Applications & Engineering Value
These No. 10 self-drilling screws are engineered to solve critical challenges in fastening sheet metal and aluminum components. The 18-8 stainless steel construction provides excellent resistance to rust and corrosion, which is vital for outdoor enclosures, HVAC systems, and electrical cabinets. The thread forming (tapping) method displaces material rather than cutting it, resulting in stronger, more vibration-resistant threads that won't loosen under stress. The combination of the No. 3 drill tip and a square drive streamlines the installation process, allowing a single tool to drill, tap, and fasten, drastically reducing assembly time and the risk of worker error in high-volume production environments.
Specification Summary & Compliance
This fastener conforms to standard inch system measurements with a No. 10-16 thread and a unified thread form. The 18-8 Stainless Steel material and manufacturing process are compliant with industry standards for mechanical properties. The screw is fully threaded with a right-hand direction and features a standard pan head with a square drive (No. 2 size).
