Hex bit 1/4″ (6.3mm) deep with 50mm length.
Manufactured from quality CrV50BV30 steel, with AS-DRIVE function.
The AS-DRIVE function makes it possible to develop a greater contact force, because contact with the screw does not occur on the edges of the hexagon, but in the first third of the contact surfaces. This does not damage the screw head. A nut often loosens already damaged nuts and bolts.
