Common Accessories of Torque Wrenches


Torque wrenches are essential tools for ensuring that fasteners are tightened to the correct specifications. If you want to maximize the functionality of a torque wrench, it is important to have the right accessories.

In this article, I will show you common used accessories, including sockets, bits, extension bars, and adaptors that complement torque wrenches, allowing for versatility and precision in various applications.



Sockets are one of the fundamental accessories for torque wrenches. They are designed to fit onto the square drive of the torque wrench and thereby provide a secure connection to the fastener. The sockets are available in a wide range of sizes and are designed to fit various fastener sizes, both in imperial and metric measurements. Additionally, they are available in different shapes, such as deep sockets for reaching recessed fasteners and impact sockets for heavy-duty applications.



Bits, also recognized as driver bits or screwdriver bits, are another essential accessory for torque wrenches. They are used for driving screws and other fasteners and are available in a wide range of shapes and sizes to accommodate different types of fasteners, including Phillips, slotted, Torx, and hexagonal. When using a torque wrench with bits, it is important to ensure that the bit is securely held in place to prevent slippage and ensure precise torque application.


Extension bars

Extension bars are important accessories that extend the reach of a torque wrench, facilitating the access to hard-to-reach or tight areas. The bars are available in different lengths, providing the necessary flexibility to perform various applications. Extension bars are particularly useful in automotive and mechanical applications where access to fasteners may be limited. When using extension bars with a torque wrench, it is important to consider the added length and its potential impact on torque accuracy.



Adaptors, also known as adapters or adaptor components, are multifunctional tools that allow for compatibility between different drive sizes and types. They are used to connect sockets, bits, and extension bars to the square drive of the torque wrench. Adaptors are available in various configurations, including reducing adaptors that allow for the use of smaller drive sockets with a larger drive torque wrench, and universal adaptors that accommodate different drive sizes.

In recent years, digital adaptors are increasingly popular,with buzzers and LED indicators,which provide a more intuitive and user-friendly experience and are preferred by more people. Adaptors are essential for ensuring that the torque wrench can be used with a wide range of fasteners and applications.


Select and Use

When selecting accessories for torque wrenches, it is important to consider the specific application requirements. Factors such as fastener size, accessibility, and torque specifications will impact the selection of sockets, bits, extension bars, and adaptors. Additionally, it is important to ensure that the accessories are compatible with the torque wrench being used to ensure safe and accurate torque application.


In addition to selecting the right accessories, it is equally important to use and maintain them properly to ensure optimal efficiency and safety. Adhering to correct storage and handling of sockets, bits, extension bars, and adaptors will help prevent potential damage and ensure that they remain in good condition. Regular inspection for wear and damage is also important to ensure that the accessories continue to provide accurate and reliable torque application.



In conclusion, sockets, bits, extension bars, and adaptors are common accessories that complement torque wrenches and enhance their versatility and functionality. Even a small accessory has a role that cannot be ignored.
