What size screw should be used to attach steel sheathing to a metal structure?

• A. Self tapping #8
• B. Self tapping #6
• C. Self tapping #10
• D. Wood screw #8

Answer: (A)

Using a self-tapping #8 screw to attach steel sheathing to a metal structure is appropriate because self-tapping screws are specifically designed to create their own holes in metal materials, which is essential when working with steel sheathing. The #8 size strikes a balance between strength and compatibility with typical gauge steel, ensuring a secure attachment without risking damage to the material or inadequate holding power. Additionally, self-tapping screws are particularly beneficial in applications involving metal since they reduce installation time and the need for pre-drilling, making the fastening process more efficient. The #8 designation also provides the necessary diameter and thread engagement to properly secure the sheathing against the metal structure, contributing to the overall integrity and stability of the assembly. Other options, such as a self-tapping #6 or #10 screw, may either lack sufficient holding power or be too large, respectively, for optimal use in this context. A wood screw is not suitable due to its design, which is not intended for metal applications.
