3pcs Universal Socket Set

It features a wide range of adjustability that will fit standard 1/4-inch to 3/4-inch and metric 7mm to 19mm nuts and bolt heads.

The tool's socket contains 54 hardened steel spring pins for long-lasting durability. When placed onto a fastener, the center pins retract and the outer pins surround the fastener.

As the fastener is turned, the torque is transmitted through the outer pins to the walls of the socket, making this socket an ideal choice for heavy-duty personal or professional use.
