Help! Problems installing chin up bar in doorway! How do you get the screws in all the way? - chin-up strips

I have 1 / 16 drill bit, such as ordering instructions. Bit 1 / 8-is definitely too big for the job. There is less resistance to tighten the screws. I use all my strength and my power is annoying. I've tried screwing with the drill, but the fast lap and tighten the screws if I do not watch out. I could get a all the way until today. Suggestions?
