A screw has a long and thin metal shaft with threads spiralling along its length. It also has a turning head with a groove where a screwdriver can be used to rotate the screw.
The strength of a screws hold depends on the width of the threads and the distance between them. The closer and wider the threads, the stronger the hold will be.
However, more threads require more rotations to attach the screw and wider threads require more force in the rotations.
It s a very gud website , And has very gud info too
A screw is one of the most commonly used mechanical devices in the world. It is a machine that converts rotational motion into linear motion.
omg dis is totes the bae i just copy and past all the informashun for my homwork thank yuo

The mechanical advantage of the screw increases when the angle of the spiral increases.
This is a. Very good website. I saw this screw video on YouTube and i clicked on it i thaught this would be great for my project in school so i checked the website and it is great
