Which tool is used to extend the reach of a socket in mechanical applications?

The tool used to extend the reach of a socket in mechanical applications is an extension. Extensions allow you to connect to a socket and increase its reach, making it easier to access hard-to-reach bolts and fasteners. This is especially useful in situations where space is limited, or when the fastener is located in an awkward position that a standard socket alone cannot reach effectively.

Extensions come in various lengths, and they can be combined with other sockets to create even more versatility in handling different mechanical tasks. This is critical in automotive work, construction, and maintenance, where access to fasteners is often restricted due to space constraints. By employing an extension, you can enhance both efficiency and effectiveness when working on mechanical assemblies.
