A screw is a combination of two simple machines: A wheel (the screw rotates about its axis) and an inclined plane (the thread of the screw) It is also used when the experiment goes wrong. ("Screw this, I'm going home")
In romanian, "surub" [Shurub] means "screw". Not to "screw somebody", but like in "tightening the screws"
it means that whatever it is its not fair
The letters on a screw refer to the type of screw head and the size of the screw. For example, "PH" typically indicates a Phillips head screw and the following number represents the size of the screw. Other common letters include "SL" for slotted screws and "Hex" for hexagonal screws.
It is a very basic and childish insult.
There are all sorts of screw diameters - major, minor, pitch, mean, etc., but in general a screw diameter is a called by its nominal diameter which is the major diameter of the screw, approximately. For example a 1/2 inch screw has a nominal diameter of 1/2 inch.
