To better understand how to use and choose the right wrench, the article below will help you solve these problems.

What is a wrench?

Wrenches are commonly used in assembly and repair work, especially in the mechanical and construction industries. The highlight of the wrench is the ability to adjust the size of the clamping jaw, making it easy to work with a variety of screws or bolts of different sizes.

Wrench types are designed with many designs and features, such as regular wrenches, tooth wrenches, or chain wrenches, to meet diverse usage needs. The handle is often covered with a layer of plastic or rubber, providing a comfortable and anti-slip feeling during use.

Regarding materials, wrenches are often made from high-quality metals such as alloy steel or chromium-vanadium, helping the product to be highly durable, rust-resistant and able to withstand large impacts. These characteristics make the wrench one of the tools of professional workers.  

Structure of wrench

In terms of structure, wrenches are often made from high-strength materials such as steel, iron or alloy. This tool has three main parts: handle, width adjustment button, and movable jaw. The handle is firmly designed, creating comfort and convenience when used. The adjustment button allows flexible clamping jaw size changes, suitable for many different sized bolts and screws. The mobile clamping jaw includes serrated jaws, combined with an adjustment button to create the necessary width and tightening force, ensuring efficiency during use.

Classification of wrenches

On the market today, wrenches are divided into three popular types, meeting the diverse needs of users:

Regular wrench:  

This is the most basic type of wrench with a structure including a movable clamping jaw, a fixed clamping jaw and a roller to adjust the width. Convenience and ease of use make wrenches often become indispensable tools

Serrated wrench:  

This type has additional serrations to help increase grip and tightening ability. Serrated wrenches are often divided into many types such as regular, horizontal, or hexagonal, suitable for jobs requiring high precision. The strength of this type is its good holding ability, ensuring efficiency during the tightening process.

Chain link wrench:

This type possesses a special design with curves and links, allowing the opening diameter to be flexibly changed. The outstanding advantage of chain wrenches is their ability to withstand high tensile forces, suitable for handling tasks that require durability.

What are wrenches used for? 

Wrench is mainly used to clamp, screw or disassemble nuts and bolts of different sizes. In the mechanical industry, wrenches are used to assemble and repair machinery and equipment.  

In addition, wrenches are also popular in the construction industry, helping to tighten metal connections or fix joints. In the home, wrenches are often used to repair electrical and water equipment, install furniture or handle daily chores.
