Manufactured and designed in accordance with DIN3113A.
The 12 point ring end is set at a 15 degree angle to facilitate use on flat surfaces. This system helps to prevent damage to nuts and bolts and makes it possible to grip nuts and bolts which already have damaged corners. All ring heads are equipped with Teng Tools "hip grip" system, which means the contact surface grips on the flat surfaces of the nut or bolt head rather than on the corner.Sizes: 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 32mm.
