Increased Length: Compared to ordinary 1 - 1/2 - inch hexagon pneumatic sockets, the extended - length type has a notable feature of additional length. This enables it to reach locations that are difficult for ordinary sockets to access, such as deep holes, the interiors of pipes, or other confined spaces where bolts and nuts need to be tightened or loosened.
Efficient Torque Transmission: Despite the increased length, it can still transmit torque efficiently. It is made of high - strength materials and features an optimized structural design to ensure that when driven by a pneumatic tool, the torque is accurately and stably transmitted to the fastener, enabling reliable tightening and loosening operations and reducing slippage and torque loss.
Expanded Scope of Application: Thanks to its extended design, it can be applied to more special scenarios. In the fields of automotive engine repair, the internal assembly and maintenance of large - scale mechanical equipment, and the connection of some deep - seated structures in the construction industry, it can play a role that ordinary sockets cannot replace, improving the versatility and applicability of the tool.
High - Quality Material: It is usually made of high - quality alloy steel, such as chrome - molybdenum steel or chrome - vanadium steel. Through strict heat treatment processes, it has high hardness, high strength, and good toughness. This enables the socket to not only withstand high torque but also resist wear, impact, and corrosion, prolonging its service life and adapting to various harsh working environments.
Fine Surface Treatment: Its surface is finely treated, such as by chrome - plating or nickel - plating. This not only gives it an attractive appearance but also effectively prevents rust and corrosion. At the same time, it reduces the coefficient of friction between the socket and the fastener, making it easier to put on and take off the socket, reducing operating resistance, and improving work efficiency.
