Very often screws are thought of as the answer to all common connections, however, screws have very little shear strength as compared to nails. screws should be typically used to join two media, either like or not. To get the best connection using screws, holes should be drilled in both peices, for instance, if you are securing two pieces of wood together it is best to have a clearance hole very slightly larger than the threads but smaller than the head in the outer piece, where as the inner pilot hole should be drilled the same size as the shaft of the screw or smaller in softer wood. this allows the threads to grab only the inner material and the head of the screws holds the outer material. If the threads grab both materials you will not get as a secure bond of both pieces.
it makes it easier by doing less work for you also use a screw driver MISERABLE AT BEST♥
I think the opposite
The simple machine in this case is a wedge. The threads and cap of the screw work together to wedge two materials together.
It holds things together like wood, while a nail would not work as good as a screw because, a nail might fall out.
the screw gauge is an instrument which is used to measure length of an object.... the least count of an screw gauge can be found as follow.... l.c= pitch of the screw gauge no of divisions on main scale
because they help peoples work properly
no

That screw won't work. Hand me that longer screw, please. It'll just take a moment for us to screw in that light bulb! I screwed up. Screw it!

There is a type of bit that can cut into the remaining screw head that may help, but otherwise the screw needs to be drilled out.

Screws have things called threads and when you twist them into something, they get stuck inside. They work best with wood. Answer The thread on a screw allows it to PULL itself into say a piece of wood. No pressure is needed on the screw driver, just to turn it will be sufficient. The screw does all the work.

The screw will stick to the screwdriver. There is also a tool known as a screw set, it claps on the top of the screw. These have more control of the screw. And you odds of losing the screw are less.
You can prevent a ball screw from falling by using some adhesive on the ball screw connection. This can help to ensure that the ball stays on.
Used as fasteners, a fan or ships propeller is a form of screw, etc.
