### Unique Extension Rod Design
#### Flexible Extension
By connecting the socket with an extension rod, the length can be flexibly adjusted according to work requirements. It can easily reach into narrow spaces or operate at a long - distance, such as inside large equipment or deep in pipes. This solves the problem that ordinary sockets can't reach these areas.
#### Convenient Storage and Portability
The extension rod and the socket are detachable. When not in use, they are easy to store, taking up little space and are convenient to carry to different workplaces.

### Magnetic Function
#### Adsorb Parts to Prevent Falling
It is equipped with a built - in magnetic device that has a good adsorption force on 3/8 - sized hexagonal bolts or nuts. During operation, it can effectively prevent parts from falling. Especially when working at heights or in complex environments, it can avoid part loss and safety accidents.
#### Facilitate Part Handling
Magnetic adsorption makes the parts more firmly fixed on the socket. It is convenient to pick up and place the parts from the tool rack and also facilitates accurate alignment and installation during the operation.

### Wide Range of Applications
#### Suitable for Both Industrial and Civil Use
It is widely used in industrial fields such as automotive maintenance and mechanical manufacturing, and is also suitable for home maintenance and DIY projects. As long as it involves the operation of 3/8 - sized hexagonal bolts or nuts, it can play its role, featuring strong versatility and practicality.
#### Applicable in Various Scenarios
Whether in a regular workshop environment, an outdoor construction site, or a home garage and other different scenarios, it can provide users with a convenient and efficient solution for bolt and nut operations.
