Which type of fastener is recommended for attaching steel studs to runners?

The recommended fastener for attaching steel studs to runners is typically pan head screws. These screws are designed with a rounded, shallow head that provides a larger bearing surface, allowing for better grip and stability when fastening steel components together. Their design aids in preventing the fastener from easily stripping out of the material.

Pan head screws are particularly suitable for metal applications, as they can be used with self-tapping threads which help to pierce through the metal, creating a secure connection without pre-drilling in many cases. This is crucial in steel framing, where ensuring a solid attachment is essential for structural integrity.

In contrast, flat head screws are more suitable for applications where a flush surface is desired and may not provide the best performance in metal-to-metal connections. Hex bolts are typically used in applications requiring stronger joint connections and with nuts for securing, and they might not fit the need for quick assembly of steel studs to runners. Nail guns, while useful in wood framing, are generally not the preferred method for metal studs due to the potential for misalignment and insufficient holding power. Therefore, the choice of pan head screws aligns well with the requirements of securely fastening steel studs to runners.
