Investments That Pay Off in the Long Run
New investments should offer sustainable added value—for example, through simpler and faster setup, the reduction of potential hazards, or a more ergonomic workplace design. Longer tool life and improved product quality are also among the desired benefits. Solutions that meet several of these requirements simultaneously are particularly attractive. With JAKOB’s clamping elements, this is often the case thanks to their innovative and well-designed internal mechanism.

SC Power Clamping Screw – High clamping force with minimal effort
The heart of the SC Power Clamping Screw is its unique internal mechanism: a specially developed wedge clamping system. This system acts as a powerful force multiplier and enables extremely high clamping forces while requiring low tightening torques. The simple, manual operation ensures maximum operational safety.

The SC series power clamping screws are suitable for a wide range of applications—including presses, punching machines, machine tools, fixture construction, and equipment design. Various sizes with graduated thread diameters and clamping forces allow for selection based on specific needs.

Self-locking wedge clamping system with versatile applications
Thanks to their special geometry, SC clamping screws are self-locking in any clamping position and offer a clamping stroke of up to 3 mm. This allows clamping forces up to the nominal value to be reliably achieved, regardless of the tightening torque.

Special Version SC 100 – Maximum Performance with Simple Operation
In addition to the standard versions with thread diameters of M36, M48, M64, and M80, JAKOB offers the SC 100 special version. It achieves a maximum clamping force of 250 kN with an M100 × 6 thread—and does so with a tightening torque of just 130 Nm.

Operation is simple using a 14-mm hex key. For precise and repeatable clamping force values, the use of a torque wrench is recommended.

Custom solutions available upon request
For special requirements, custom threads are also available upon request. This allows for the implementation of customized and precisely tailored solutions.
