A socket wrench, also known as a spanner in British English, is a versatile tool used for turning fasteners, such as nuts and bolts. It consists of a handle and interchangeable sockets of various sizes and shapes, which can be attached to the handle using a ratchet mechanism. This design allows for precise and efficient tightening or loosening of fasteners in a wide range of repair and construction tasks.
The socket wrench provides several advantages over traditional wrenches. Its ability to accommodate different socket sizes eliminates the need for multiple wrenches, saving time and effort. The ratchet handle enables continuous rotation without the need to reposition the tool, making it ideal for tight or hard-to-reach spaces.
Sockets & Socket Sets
Socket sets include a variety of socket sizes, usually provided in both standard (SAE) and metric measurements. These sockets are typically made of hardened steel and come in different shapes to fit a variety of fasteners. They can be six-point (hexagonal) or twelve-point, and may be deep sockets or standard length. The choice of socket to use depends on the specific fastener you are working with. For example, a six-point socket provides more contact area and is better for handling high torque applications, while a twelve-point socket is easier to position. Always ensure you use the correct size socket for the fastener to prevent slipping and rounding off the corners of the bolts or nuts. 
Working Principle of Socket Wrench
The working principle of a socket wrench revolves around the concept of leverage and rotational force or torque. The socket is attached to the ratchet handle and fits over the nut or bolt you want to turn. When force is applied to the ratchet handle, the ratchet mechanism inside the handle rotates the socket in one direction (tightening or loosening the fastener) but does not rotate it in the opposite direction. This ratcheting action allows you to keep the socket in place on the fastener while you reposition the handle, making it more efficient than a regular wrench in tight spaces or when large amounts of torque are required. Remember to set the direction of the ratchet correctly before beginning; turning it one way tightens the nut or bolt, while turning it the other way loosens it. 
Using a Socket Wrench Effectively
To use a socket wrench effectively, begin by selecting the proper socket that fits the bolt or nut you are working on. Ensure you match the measurement type (SAE or metric) to the fastener. Attach the chosen socket to the ratchet handle. If you are tightening the fastener, position the ratchet so you are turning it in a clockwise direction. For loosening, it should be counter-clockwise. Place the socket onto the fastener and hold the ratchet handle at its end to maximize leverage.
Begin turning the ratchet handle. Due to the ratcheting mechanism, you can swing the handle back without turning the socket. This is particularly useful in areas with limited space where full rotations are not possible. Keep repositioning the handle and turning until your task is complete. Always remember to apply steady, balanced pressure to prevent slipping that could potentially damage the fastener or cause injury. When done, pull the socket off the fastener. Remember to clean and store your socket wrench and its parts properly to ensure their longevity. 
Tips and Techniques for Socket Wrench Maintenance
Maintaining your socket wrench and its components is crucial to ensure their long-term functionality and reliability. Always clean your socket wrench after use to remove any dust, dirt, or grease that may have accumulated. You can use a cloth and a mild solvent or degreaser for this purpose. For stubborn dirt, a small brush might be helpful. Make sure to dry each part thoroughly after cleaning to prevent rusting.
Periodic lubrication of the ratchet mechanism is also necessary to keep it operating smoothly. You can use light machine oil or a specific tool lubricant for this. Apply a small amount of lubricant to the moving parts inside the ratchet mechanism, but avoid over-lubricating as this can attract dust and grime.
In terms of storage, it’s best to keep your socket set in the case that it came with, or purchase a dedicated socket holder or toolbox. This will protect the set from damage and make it easier for you to find the right socket when needed. Lastly, always remember that although socket wrenches are durable tools, they’re not indestructible. Avoid using them as hammers or pry bars, and do not apply excessive force or use extensions on the handle to increase leverage, as this could damage the tool or even pose a safety risk. Proper care and handling will ensure your socket wrench remains an effective and valuable part of your toolkit for many years.
