wrench

A wrench is a tool used for tightening or loosening nuts and bolts. It's frequently used for fixing bicycles or assembling furniture.

These days, it has become an essential tool commonly found in homes. It's become even more important with the increasing popularity of ready-to-assemble furniture.

The history of the wrench dates back to the Industrial Revolution. As mechanization progressed, the need for precise tightening tools grew, leading to the development of the wrench. In modern times, various types of wrenches have been developed and are used for specific purposes.

Recently, innovative products like smart wrenches and self-adjusting wrenches have emerged. With the spread of DIY culture, they are evolving into tools that anyone can easily use. In particular, they are increasingly being used by the MZ generation for self-interior projects and hobbies.
