Tensioning nut with T-knob D=M16 hardened steel, Components: aluminium

Material:
Hardened steel housing, aluminium cover, thermoplastic star knob and T-knob.
Version:
carbonitrided. Black star knobs and T-knobs.
Order example:
K2507.4010
Note:
Clamping nuts with star or T-handle knobs are a new development based on the self-locking clamping nut K2506, which has proven itself in a wide variety of fields. The control hexagon has been replaced by a star knob or T-handle and supplemented by an additional mechanical latching system. An integrated planetary gear acts as a force multiplier. The mechanical latching system makes automatic switching from the advance stroke to effective force application possible. In this way, considerable clamping forces can be achieved with the simplest manual operation, without the use of additional ring (box-end) spanners or socket wrenches. The robust design and the self-locking function ensure high operational safety. Clamping nuts can be used not only in mechanical engineering but also universally in applications with high clamping and locking forces, requiring little effort. Under normal conditions of use (max. 120 °C), the clamping nuts are maintenance-free.

The strength class of the threaded pin must be at least Q 10.9. For thread diameters smaller than M16, threaded pins with strength class 12.9. must be used In addition, the maximum permissible static load must be reduced.
Advantages:
- Simple manual operation.
- High clamping forces through force amplification.
- Quick installation thanks to the automatic switching mechanism.
- High operational safety through self-locking.
