Hello, everybody.
We're soon going to have a new metal garage, and in order to have pegboard, shelving, etc, I'll have to attach 2x4's horizontally to the metal tubing that supports the structure. The tubes are 12gauge galvanized, and I'm wondering about the best fastener to just screw the 2x4's right to the tubes.
The manufacturer uses 1/4" TEKS screws to attach the walls to the tubing; 1/4" seems like overkill for this, but I'm not sure. Any suggestions?
