In the package I received 01/17/2023 there weren't any screws or any instructions, but as I've just moved into an older house that I purchased at the beginning of 2023 it turned out to be similar to the installation of Venetian blinds that was needed. As part of the installation of the Venetian blinds I purchased a DeWalt drill at Lowe's that I saw was rated reasonably well by Consumer Reports. I actually had additional screws that were I suppose just included as extras in the Venetian blinds packages, and so those fit the holes in the mezuzah. The drill bit that I used was a 1/8" one, and I don't have measurements of the exact length or diameter of the screws I used but doing some quick Google searches it looks like that drill bit goes with screw sizes generally in the range of #8, #9, or #10. One needs to make the marks for the holes at a good level of precision or else they won't line up well enough. The pen that I had didn't have a point that was both thin enough and long enough to fit into the hole and make a mark, and so I initially tried my best to just estimate it after moving the mezuzah to the side. I found a better way which is to use a bamboo skewer. (I had purchased a set of bamboo skewers at a regular grocery store nearby for other reasons. They were in the baking section with measuring cups, etc.) The bamboo skewer was both thin enough and long enough to fit through the hole and make a mark. Other things like maybe a thumbtack or a clothes pin, etc. could work as long as it's both thin enough and long enough. I didn't try a pencil which I didn't have, but that might be the easiest and most natural choice. If it's just one person, as it was for me, one could do the following: 1. Mark and drill one hole, and then affix the mezuzah in place using one screw in that one hole, but so that it can still rotate about. 2. Rotate and position the mezuzah in a way that seems reasonable, and make the second mark using a pencil, bamboo skewer, etc. 3. Rotate the mezuzah out of the way so that it's possible to drill the second hole, and then affix the mezuzah in place by screwing the second screw into the second hole.

Found this beautiful mezuzah in a ‘Ten Thousand Villages’ near me. I was very taken in by it’s beauty and craftsmanship. I have many doors and will be back for more Many thanks to the artist!
