Why are there so many different kinds of screw heads?
Answer: The primary reason for the wide variety of screw head drive types is to ensure the fact that you will never have the proper screwdriver close at hand when you need it.
What is the difference between types of screws?
The visible difference is in the thread. Woods screws have a wider-spaced, medium-depth screw. Some wood screws – longer ones – often have a threadless shank at the top of them. Sheet metal screws, on the other hand, always have a tighter, sharper thread that cover their entire length.
How do I know what kind of screws to use?
The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16. Most of the time you’ll want to go with a #8 screw.
Why are some screws Phillips?

This screw head type is arguably the most commonly found in nearly any application. Not only do electric screwdrivers speed up the process, they also help ensure the screw is straight.
