  • Interesting fact: The term 'screwing' was derived from the activities of pigs. A pig's member screws.
    • Screw A cylinder, or a cylindrical perforation, having a continuous rib, called the thread, winding round it spirally at a constant inclination, so as to leave a continuous spiral groove between one turn and the next, -- used chiefly for producing, when revolved, motion or pressure in the direction of its axis, by the sliding of the threads of the cylinder in the grooves between the threads of the perforation adapted to it, the former being distinguished as the external, or male screw, or, more usually the screw; the latter as the internal, or female screw, or, more usually, the nut.
    • Screw A small packet of tobacco.
    • Screw A steam vesel propelled by a screw instead of wheels; a screw steamer; a propeller.
    • Screw (Math) A straight line in space with which a definite linear magnitude termed the pitch is associated (cf. 5th Pitch, 10 ). It is used to express the displacement of a rigid body, which may always be made to consist of a rotation about an axis combined with a translation parallel to that axis.

    • Screw Specifically, a kind of nail with a spiral thread and a head with a nick to receive the end of the screw-driver. Screws are much used to hold together pieces of wood or to fasten something; -- called also wood screws, and screw nails. See also Screw bolt, below.

    • n screw The hole in which a screw (in sense 2) turns.
    • n screw A cylinder of wood or metal having a spiral ridge (the thread) winding round it, usually turning in a hollow cylinder, in which a spiral channel is cut corresponding to the ridge. These convex and concave spirals, with their supports, are often called the screw and nut, and also the external or male screw and the internal or female screw respectively. The screw forms one of the six mechanical powers, and is virtually a spiral inclined plane—only, the inclined plane is commonly used to overcome gravity, while the screw is more often used to overcome some other resistance. Screws are right or left according to the direction of the spiral. They are used for balancing forces, as the jack-screw against gravity, the propeller-screw against the resistance of water, ordinary screws against friction in fastening pieces together, the screw-press against elasticity, etc.; and for magnifying a motion and rendering it easily manageable and measurable, as in the screw-feet of instruments, micrometer-screws, etc. For the pitch of a screw, see pitch, 7 . See also leading-screw, leveling-screw.

    • n screw A mechanical loader for handling and lowering bales of cotton into the cargo-space of vessels.
    • n screw A screw placed against the edge of a disk and fitting into helical teeth formed on that edge, so that when the screw is turned a very fine angular motion of the disk results. It also acts as a clamp to prevent angular motion except when the screw is turned. It is used for index plates in gear-cutters to divide the circle into aliquot parts and on the graduated limbs and verniers of astronomical, surveying, and other instruments.
