Hi! I just used a powerdrill for the first time, but I’m having a lot of difficulty getting the screws to go in far enough to become flush with the wall. Does anyone have any insight on how to get them to drill in right? Mine are still hanging out some even though they seem to be in the wall straight, and the drill or screwdriver wont let me press them in further. I’m trying to attach a metal hook w/a backing to my outside wall so I can lock my bike up to it if I’m just locking it up to go back out momentarily. Thank you!
