Which statement about light gauge steel framing joinery is accurate?

• A. It is typically joined with nails
• B. It is typically welded at all joints
• C. It is typically joined with self-drilling, self-tapping screws
• D. It requires no fasteners

Answer: (C)

Light gauge steel framing is connected with fasteners that can thread into thin steel without requiring a separate tapping step. Self-drilling, self-tapping screws are designed to cut their own threads as they are driven into steel studs and tracks, so there’s no need for pre-drilling or separate tapping. This makes on-site assembly quick, accurate, and reliable for metal-to-metal joints, and it supports consistent load transfer through the frame. Nails are not the typical choice for these steel joints because they don’t hold as well in steel and can loosen under load, and welding at all joints is not practical or desirable due to heat distortion, complexity, and the need for removable or adjustable connections. Using no fasteners would fail to provide any load transfer or structural integrity. Thus, the standard practice is to join light gauge steel framing with self-drilling, self-tapping screws.
