YATO Hexagonal Deep Socket 27mm 1/2"Dr YT-1238 PL

The hexagon profile uses a special treatment called AS DRIVE, which allows to develop a greater contact force, as the contact with the screw does not occur at the edges of the hexagon, but in the first third of the contact surfaces. This prevents the bolt head from being damaged and the nut often loosens nuts and bolts that have already been damaged.
