I need to replace some old door hinges and the current hinges only have 2 of the 4 holes drilled. I am installing 4x4 self closing hinges and want to have all the screws installed. Problem is I did a dry run on a different door and the machined screws don’t pull the hinge to the door tightly, they get to a certain point and just spin. Obviously I don’t know what I’m doing. I’d like to know what equipment I need, what size screws, what size bits, the works. The door is a residential door, most likely hollow with insulation on the inside.
