1" hand sockets are commonly used in truck maintenance, aviation, railway, and heavy industrial applications. Among standard hand socket drive sizes, 1" sockets provide the highest torque capacity and are designed for large fasteners and demanding working conditions. Due to their high torque capability, they are generally larger and heavier than smaller drive sockets.
Common 1" sockets include 6-point and 12-point sockets. Available metric sizes range from 36 mm to 80 mm, making them suitable for heavy-duty repair, maintenance, and industrial fastening applications.
