Sockets are hand tools attached to the socket wrench or ratchet’s end designed to tighten or loosen a wide range of fasteners by turning them. They are the essential tools, usually constructed from rugged steel, that provide more torque than spanners. They are ideal for a wide range of applications depending on the environments they are used for. In addition, they come in various sizes to suit a specific purpose or task.
How Do Sockets Work?
Sockets work effortlessly in combination with ratchets. They snap onto the ratchet’s end on the square-drive connector side while the other end fits the fastener. The ratchet then engages and tightens the fastener by allowing the socket to turn the fastener clockwise. At the same time, the anticlockwise turning of the socket loosens the fastener.
From which Materials are they Made?
These hand-operated tools are made from highly durable and solid materials for high leverage and torque, including:
- Steel
- Chrome vanadium
- Stainless steel
- Vanadium steel
- Chrome alloy steel
- Beryllium copper
- Alloy steel
- Chrome extra
- Aluminium bronze, and more.
What are the Popular Drive Sizes of Sockets?
The drive size depends on the size of the socket you carry. The larger the socket size, the larger the drive size it would require due to the force to be applied. However, the most common and popular drive sizes include 1 in, 1/2 in, 1/4 in, and 3/4 in.
Types of Sockets
They are divided into various types with their specific applications and include:
- Hex Sockets: Hex is derived from hexagon, and they fit naturally around six-sided nuts or bolts. They are further sub-divided into two hex socket types: 6-point and 12-point. They offer high flexibility, especially in confined spaces.
- Deep sockets: Deep sockets (also called deep dive sockets) are designed to provide easy access to hard-to-reach spaces and are longer than standard sockets.
- Pass-through sockets: They are different from other types of sockets in terms of their design and function. They feature a hollow design, allowing long fasteners to pass through and tighten or lose longer bolts and nuts.
- Spline sockets: They are ideal for tightening or loosening splines as well as hex fasteners. They are distinguished tools due to their higher torque and versatile use for a wide range of different fasteners.
- Spark plug sockets: As the name suggests, they are ideal for removing or fixing the engine’s spark plugs. They feature rubber inserts seated within integral socket parts that prevent the engine and socket from being damaged.
- Insulated sockets: They are ideal sockets for electricians and maintenance engineers to protect them from electrocution or shock. They provide insulation and work safety on live equipment up to 1000 V.
What are the Uses of Sockets?
Sockets offer a wide range of applications in various environments, including:
- Workshops and Garages
- Marine Maintenance
- Civil Engineering
- Aerospace Industry
