It feels solid. **Q: recommended screws? I'd like to use some quality screws but have no idea what to look for, brand, size, etc** A: Comes with some very well impressive screws so no need to worry. You are in good hands with this baby. I tried as best I could to kick it in and was rewarded with boot marks and a trip to HD to get a solid wood door. Any unwelcomed intruder would need a some serious tools to get in. Make sure your locks are unpickable too.
