Screw

A screw, or bolt, is a type of fastener characterized by a helical ridge, known as an external thread or just thread, wrapped around a cylinder. Some screw threads are designed to mate with a complementary thread, known as an internal thread, often in the form of a nut or an object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects.

Famous quotes containing the word screw:

    “Cham” is the only thing to screw one up when one is down a peg.
    Anthony Trollope (1815–1882)

    Oh come home soon, I write to her.
    Go screw yourself, is her answer.
    Now what is that, for Christian word?
    I hope she feeds on dried goose turd.
    Robert Creeley (b. 1926)

    Let us have a good many maples and hickories and scarlet oaks, then, I say. Blaze away! Shall that dirty roll of bunting in the gun-house be all the colors a village can display? A village is not complete, unless it have these trees to mark the season in it. They are important, like the town clock. A village that has them not will not be found to work well. It has a screw loose, an essential part is wanting.
    Henry David Thoreau (1817–1862)
