A material covering a hole is called a patch. It can be used to repair damage or prevent something from escaping.
The hole into which a screw is inserted is called a pilot hole. This hole helps to guide the screw into the material and prevent it from splitting or cracking. It also makes it easier to drive the screw in.
It would be a hole punch.
Event horizon, not event - and it's called the accretion disk.
I knew a watering hole called Brian. His brother was called Jim
After a high mass star explodes, the leftover material forms a remnant called a neutron star or a black hole. If the core of the star is less than about 3 times the mass of the Sun, it collapses to form a neutron star. If the core is more massive, it collapses further, causing the gravitational collapse to form a black hole.
escutcheon
A small piece of material fixed to another,or to repair something by adding a piece of the same material.
patch
A reamer concentrically enlarges a hole in a thin-ish piece of material.
It would be very difficult for the Sun to get a hole in it... The material that makes up the Sun is so hot that it resides in a state of matter called plasma. This material does not have the rigitity that a solid has as to allow a piece to go missing, the plasma would "flow" into unoccupied space.

Covering all holes would be a C. Also covering the hole at the back and the second hole (a treble C)

To fix a hole in the floor, you can follow these steps: Clean the area around the hole to remove any debris or dirt. Cut a piece of plywood or a similar material to fit the size of the hole. Apply adhesive to the edges of the hole and place the cut piece of material over it. Secure the patch in place with screws or nails. Fill any gaps or cracks with wood filler or a similar product. Sand down the patched area to make it smooth. Paint or stain the patched area to match the rest of the floor.
It really depends on the material you are drilling. Thinner material will use a smaller pre-drill bit. Try drilling a sample hole on a piece of scrap or where it will not be visible Then try your screw. Adjust your hole size if necessary
Threaded inserts are installed in a piece of equipment by first drilling a hole in the material, then inserting the threaded insert into the hole using a special tool or machine. The insert is then secured in place by either pressing, screwing, or heating it to create a strong and durable connection.
