Bosch Square Drive 1 Inch, Stainless Steel Socket for Impact Wrench

A socket is a fundamental component in various mechanical and electrical systems, serving as a connection point for inserting plugs, bolts, or other fasteners. It consists of a hollow, typically cylindrical cavity designed to receive a corresponding protrusion or fitting. Sockets come in a wide array of shapes, sizes, and materials to accommodate diverse applications across industries such as construction, automotive, electronics, and household maintenance.

In mechanical engineering and construction, socket wrenches, also known as ratchets, are commonly used to tighten or loosen nuts and bolts efficiently. These sockets typically feature a square drive fitting that interfaces with a ratcheting mechanism, allowing users to apply torque with ease. The socket's interior features a hexagonal or square-shaped recess, matching the profile of various bolt heads or nuts. This design ensures a secure grip and reduces the risk of slippage or damage to the fastener.

In electrical engineering and household contexts, sockets refer to receptacles designed to receive plugs from electrical devices. These sockets are integrated into electrical wiring systems and are standardized to ensure compatibility with a wide range of appliances and devices. Common types of electrical sockets include wall outlets, extension cord sockets, and power strips, each designed to accommodate specific plug configurations and voltage requirements.

Sockets are manufactured from diverse materials depending on their intended application. Steel, chrome vanadium, and other alloys are commonly used in the production of mechanical sockets due to their strength, durability, and resistance to wear. Electrical sockets, on the other hand, often feature insulating materials such as plastic or ceramic to prevent electrical shocks and ensure user safety.
