F-series 

F-series clamps are designed for heavy duty machining when extreme clamping force is required. Though small in size, they have an amazing clamping force of up to 150 kN.

With F-series clamps, it is important to use a torque wrench to avoid potential damage to workpieces due to excessive force.

F-series clamps are designed for an M16 socket head screw (in inch measures, we recommend the use of a 5/8" screw).
