D-series clamps are designed for M12 socket head screw. For single-wedge clamps in inch measures, we recommend use of ½ -13 x 1 1/4 socket head screw and for double wedge clamps ½ -13 x 1 ½ screw.

Due to a low-profile design of OK-VISE clamps, it is possible to execute flexible three-directional machining of workpieces with one fastening. This ability to machine a workpiece in three planes means improved accuracy, reduces the need for quality control measures and increases opportunities for further processing.

D-series clamps are also available in inch versions. The center hole in the wedge is wider in order to fit the half-inch socket head screw. These models are available on request.

DK2-VT-B clamp has a self-adjustable steel ball inserted into a clamp jaw. The steel ball is equipped with a torsion protection allowing the ball to self-adjust up to 9 degrees. This makes clamping of inaccurate parts and castings more flexible. Inch model is calledDK2-VTI-B.

The key feature of the OK-VISE low-profile clamp is its cross-wedge construction in both the horizontal and the vertical plane, which means that the clamp is locked firmly in every direction as it is tightened down. This cuts out all possibilities of measurement error due to sliding.

DK2-VT comes with serrated jaws and the inch model is called DK2-VTI.

DK2-VT+5 comes with soft jaws (30-34 HRC) and they can be machined to fit the geometry of the workpiece. In this model each jaw is machinable up to 5 mm, yet not weakening the structure of the jaw itself. Inch model is called DK2-VTI+5.

When the single-wedge clamps keep the workpieces steadily in one place, not allowing upward or downward movement, the double-wedge clamps generate a pull-down action pressing the workpieces also towards the fixture base.   DK2-WT comes with serrated jaws and the inch model is called DK2-WTI.
