What size screw will work this braket
1
For the 4 holes (2 on each side) that secure into the 2x4's, I used #8-1¼ self-drilling sheet metal screws. As for the two smalle holes at th3 top used to secure the crossbar is something I haven't figured out yet. I know for sure it's smaller than #6 screws so I'm thinking #4-1½? I plan to check again this weekend.
