- Superior corrosion resistance provided by 18-8 Stainless Steel with a Galvanic Barrier Coating, ensuring long-term durability in harsh environments.
- Maximum holding power from a fully threaded design and thread forming action, creating strong, reliable connections.
- Optimized for high-speed driving with a No. 2 Phillips flat head, reducing cam-out and improving assembly efficiency.
- Precise thread engagement with a right-hand thread, 0.19" diameter, and 16 threads per inch for consistent, secure fastening.
- Versatile material compatibility designed for joining sheet metal to wood, streamlining multi-material fabrication projects.
Professional Applications & Engineering Value
These self-drilling screws are engineered to solve critical assembly challenges in HVAC, metal framing, and construction. The 18-8 Stainless Steel core provides fundamental strength, while the Galvanic Barrier Coating offers an extra layer of defense against galvanic corrosion when fastening dissimilar metals. The cutting wings and No. 3 drill point work in tandem to quickly clear material, significantly reducing installation time and labor costs by eliminating the need for separate drilling and tapping operations. This makes them an indispensable industrial fastener for projects demanding speed, reliability, and exceptional corrosion resistance without sacrificing joint integrity.
Specification Summary & Compliance
This fastener adheres to standard inch system measurements, featuring a thread diameter of 0.19" (No. 10 size) and a length of 1-1/2". The fully threaded design with a thread forming method and 16 threads per inch ensures consistent performance. The flat head with a standard profile and No. 2 Phillips drive is designed for common industrial tools. The 18-8 Stainless Steel material and coating are compliant with RoHS and REACH environmental standards.
