The number 7.
The circumference of a circle can be found by multiplying its diameter (the distance from one point on the circle to its opposite point) by the irrational number pi. The value of pi is about 3.14, but it has an infinite number of nonrepeating digits. The circumference can also be expressed as 2(pi)r, where r is the radius. The radius is the distance from the center of the circle to any point on the circle. It is equal to half of the radius.
No it is not. If you want to get a square number you must multiply a number by its self.
Self and 1
The number zero! Multiplied by itself = 0 x 0 = 0 Added to itself = 0 + 0 = 0!

Self tapping screws is one such type of screw, often known as self threading screw. The term self tapping is quite self explanatory, it basically taps into its own hole as it is driven into any material. They are extensively used in manufacturing and construction industries.
A self-tapping screw can be used to join two pieces of plastic or metal with simple holes drilled into them. A "normal" screw requires one of the holes to be "tapped" - a spiral has to be cut into one of the holes to accept the screw. Tapping holes is something of a game of skill; the tapping tools use very hard, brittle steel and it's easy to break a tool in the hole.
A HWH self-tapping screw is a type of screw that has a hexagonal head (HWH stands for hex washer head) and is designed to create its own threads as it is driven into the material, eliminating the need for pre-drilling. It is commonly used in construction and woodworking projects.
Use a self tapping screw, and screw the top plate into the grid for the ceiling tiles.

It is a self drilling, self tapping screw for steel to steel applications. For wood to steel applications, there are reamer tek screws available.
Just go to a store that has screws and ask an assistant for a self tapping screw if you are drilling a new hole. And then go home and drill it in with an electric screwdriver.
Self tapping screws are made by a few steps. You have to made the medal and then put in the details.
Use metric 6 mm or 1/4 inch self tapping screw to attach plate. ( North America only )
If they are self tapping screws, the drill bit is as thick as the solid barrel of the screw. If you want the screw to go through easily to have a nut on the other side, then the drill bit is slightly larger than thread size.
