What is a requirement for impact sockets?

Impact sockets are specifically designed to withstand high torque and the forces generated during impact driving applications using power tools like impact wrenches. One of their unique features is that they often require a through pin and an O-ring retainer to ensure that the socket securely fastens to the socket drive of the tool, preventing it from becoming disengaged during use. This design helps maintain safety and efficiency while working, as it minimizes the risk of the socket flying off and causing injury or damage.

Other features of impact sockets include a thicker construction than standard sockets, which allows them to handle the increased stress without breaking. While color coding can help in organizing tools, it is not a specific requirement for impact sockets. Additionally, being lighter than standard sockets is not a practical necessity; rather, the focus is on strength and durability. Lastly, impact sockets are typically designed to work with extensions, so having a requirement that they cannot be used with any extension would hinder their versatility and functionality. Thus, the requirement of including a through pin and an O-ring retainer is essential for ensuring safety and effectiveness in using impact sockets.
