How does a wrench work?
Basically, a wrench consists of a stout lever with a notch at one or both ends for gripping the bolt or nut in such a way that it can be twisted by a pull on the wrench at right angles to the axes of the lever and the bolt or nut.
What does a wrench and socket do?
Wrenches. A ratchet and socket combination (sometimes called a socket wrench) lets you turn a nut or bolt without repositioning the tool on the fastener — like you need to do with a wrench when there isn’t enough room to turn it in a full circle. This can make the work quicker.
What does an open wrench do?
The open ends allow the tool to be slid over the nut in tight quarters where there would be insufficient space for a box wrench or a socket, or where the length of a shaft or pipe interferes. Open-end wrenches are the quickest and easiest wrenches to use, but they will not always fit into tight quarters.
What does wrench light mean?
The wrench warning light on Ford vehicles is the powertrain malfunction indicator light. When it illuminates, it means that the computer has detected an issue with your vehicle’s powertrain or four-wheel-drive system.
What is the biggest disadvantage of using an open end wrench?
The disadvantage is that it is less stable than a fixed-size wrench and can easily injure you or damage the fastener. An adjustable wrench should be used only if the correct size wrench is not available.

What is the difference between a socket wrench and a ratchet?
Sockets are tools that attach to a rachet, torque, or socket wrench. It’s used mostly for loosening and tightening fasteners such as nuts and bolts. Once it’s secured to the ratchet the user can loosen or tighten a bolt or nut while the socket remains in place by just turning the handle of the ratchet.
What’s the difference between a ratchet and a socket wrench?
Ratchets. A ratchet is a mechanical device that only allows movement in one direction. When it is equipped onto a wrench, it allows the user to set two turning directions: one where the wrench head is fixed and one where it spins freely. In fact, many may assume that a ratchet wrench is automatically a socket wrench.
