B-series clamps are designed for M8 socket head screw. (In inch measures, we recommend use of 5/16-18 x ¾ socket head screw).

Accurate machining demands a clamp which is completely free of play. The key feature of the OK-Vise low-profile clamp is its wedge construction in both the horizontal and the vertical plane, which means that the clamp is locked firmly in every direction when it is tightened down. This minimizes all possibilities of measurement error due to sliding.

Most popular B-series models BK2-VT and BK2-VT-S are now also available as more economic models. Please check the BK2-VT-O and BK2-VT-SO models and possibilities in our O-series offering!

Thanks to a small size these light-weight clamps are easy to lift and install. Moving around from one application or machine to another is effortless. Accuracy is gained by grinding all the moving surfaces to a precise angle and conducting careful measuring with each clamping unit during the production process.  BK2-VT comes with serrated jaws and regular springs.

BK2-VT+3 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 3 mm, yet not weakening the structure of the jaw itself.

BK2-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.
