Hey there! I'm working on installing a header for a barn door and could use some advice. The header is 3/4" red oak and will have a track attached to it. The pre-drilled holes in the track don't line up with the header, so I'll need to use longer lag screws to secure the header to the studs. However, I've heard that having the lag screws go all the way through the back of the header could weaken the connection. Currently, the screws extend about 3/8" through the header. Is this okay, or should I opt for shorter screws that don't poke out the other side? Also, how deep should the lag screws that attach to the studs go? I was thinking they should penetrate about 2.5" into the wall. Does that sound right? I hope I'm not overthinking this! Thanks a lot for your input!

I can't guarantee that the strength will be compromised, but I had a heavy regular door that kept pulling screws out of the studs. After repeatedly dealing with that, I switched to machine screws with washers and nuts on the back side. No more sagging issues!
If you want a stronger hold, I suggest using actual bolts with fender washers and lock nuts on the back side. It typically provides a better grip than just screwing into the wood. Just a heads-up, though: make sure you plan for that, as you'll need enough space to accommodate the nut. If the header is flush against the wall, you may need to get creative with capping the nut!
Thanks for the suggestion! Since the header will be flush against the wall, unfortunately, I won't have enough space to install a nut behind it.
