A screw is an inclined plane over a cylinder. It is like a cylinder that has a head at one side and a nail-like design on the other side. It also comes with ridges around the surface. Ridges, also called grooves, over the cylinder are called the thread. Screws employed for holding things also drill holes in the surface. The different screw types used come with different examples of screws, like guitar tuners, light bulbs, taps, and bolts. where we will cover details for basic examples of screws.
What is a screw?
- A screw is a helical threaded fastener that is tightened or released by applying torque on the head. screws used for holding objects with different materials.
- Screws put into holes for assembly components or screws make their own thread. If we find a difference between a screw and a bolt, we find that the bolt is used for tightening through nut torquing.
- The screw head on one side comes with slots and features for transferring twisting force.
- Commonly used tools for driving screws are wrenches, hex keys, and screwdrivers.
- The head has larger dimensions than the body, and the bearing surface helps the screw to drive deeper into the surface.
- cylinder-like design of screw through underside of head to tip, known as the shank, that is threaded to some space between threads called the pitch.
- Screws tightened through clockwise rotations are called right-hand threads.

Examples of Screw Simple Machines
Screw pump
- screw pump, also called a waterscrew, and employed for moving fluid over the screw axis. A positive displacement pump replaces one screw or more screws according to requirements.
Bulb
- It rotates the bulb to the holder through the holder with a certain value of torque force for bulb movement. Thread cutting exists on the bulb base, and the inside holder is accurately configured with it, so the bulb is considered a basic example of a simple screw machine.
Jar Lid
- The threads on the jar neck and the inner side of the lid are matched with each other. The torsion force on the lid helps the lid to rotate in a circular motion to make a connection with the jar.
- If the torsion force operated in the reverse direction, then the lid would show movement in the reverse direction. A removed lid is an example of a simple screw machine.
Drill Machine
- The inner mechanical system of the drilling machine helps the drill bit to rotate and also move in a circular direction. Circular motion that is applied on a drill bit transforms into axial linear motion and defines the working of a simple screw machine.
Bolt
- • A bolt is a common example of a simple screw machine. It is a mechanical tool employed for holding two particles together through a washer and nut. The bolt comes with threads cut over the surface that match the thread on the nut’s inner design.
Faucets
- A faucet is also an example of a screw that operates as a control device for fluids. The movement of the faucet in any direction varies the water flow. that make screw examples
Car Jack
- screw jack is used for transforming rotational motion into linear motion. Threads on worm screws provide 90 degrees of force on the body according to the direction of rotation.
- The car jack is small in size and easy to carry and can handle the weight of a car.
Gas Tank Cap
- In the gas tank cap, a torsion force is applied to fix the gas tank cap on the upper part of the fuel tank, where the gas tank cap works like a simple screw machine.
Guitar Tuners
- • A guitar comes with some knobs, and these knobs, also called guitar tuners, are employed for tuning the guitar based on the guitar’s demand.
- These knobs have features for screw strings, working of the knob, and an example of a screw. Knobs come with spiral threads that help us to loosen or tighten screws.
BallpointPens
- ball pen is used for listing something on paper. The caps at the upper part of the pen refill ink when it becomes dry. This pen is also an example of a simple screw machine.
- The pen cap comes with circular threads used to loosen or tighten the cap.
Ancient Water Screw
- Greek scientist Archimedes made devices that work like pumps in the 11th century with the use of a screw in a pipe for taking water from a lower point to a high vertical point against gravity.
