A screw is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to the head. The most common uses...

A screw thread is a helical structure used to convert between rotational and linear movement or force. A screw thread is a ridge wrapped around a cylinder...

inventor John Ericsson to apply his screw-propeller to steam vessels. After several experimental versions, Clyde launched the twin-screw propeller steamer...

precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances...

The Turn of the Screw is an 1898 horror novella by Henry James which first appeared in serial format in Collier's Weekly (January 27 – April 16, 1898)...

developed in the Houston hip hop scene in the early 1990s by DJ Screw. The screwed technique involves slowing the tempo of a song down to 60 and 70 quarter-note...

At a minimum, a screw drive is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves...

a screw, which holds objects together by the restricting motion parallel to the axis of the screw via the normal and frictional forces between the screw's...

The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly...

A roller screw, also known as a planetary roller screw or satellite roller screw, is a low-friction precision screw-type actuator, a mechanical device...

called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical...

flatheads. The nose on either type of screw gun can be adjusted to countersink screws to the desired depth. The user must apply pressure to the bit to engage...

The screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical...

The bulbs have right-hand threaded metal bases (caps) which screw into matching threaded sockets (lamp holders). For bulbs powered by AC current, the...

turning screws. A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. This...

leading to this type of mechanism being less suitable for smaller compressors than piston compressors. The screw compressor is identical to the screw pump...

"buffers and screw", "screw", and "screwlink") are the de facto International Union of Railways (UIC) standard railway coupling used in the EU and UK, and...

screw-cutting lathe is a machine (specifically, a lathe) capable of cutting very accurate screw threads via single-point screw-cutting, which is the process...

lines in the same direction. The force and torque vectors that arise in applying Newton's laws to a rigid body can be assembled into a screw called a...
