B-series

B-series clamps are designed for an M8 socket head screw (in inch models a 5/16" screw is recommended) and posess a clamping force up to 25 kN.

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