Reliable screw fastening. With NAVITIGHT® to prevent damage caused by misalignment.


Installation without jamming

NAVITIGHT® corrects insertion angle errors right at the assembly stage.

If the screw threads are misaligned when a screw is inserted in the component (known as cross-threading), the internal thread may be damaged or even completely destroyed. But thanks to the special geometry of the NAVITIGHT® screw, this problem is now a thing of the past.

Method / principle

Simple principle, huge impact. NAVITIGHT®’s secret can be found in the geometry of its thread run-out: the major diameter of the narrower screw tip is smaller than the minor diameter of the female thread – while the thread pitch remains constant. So the torque that is generated when the screw is tightened brings the screw and the female thread into perfect alignment, preventing any screw-fastening errors.


These fasteners can be used in any automated or manual screw fastening applications where access to the female thread in the component is restricted.

Product benefits

Product benefits

There are many good reasons for using our products.

Strength and options.
Point by point.

Reliable screw fastening

Errors are corrected by the tapered screw tip. Even wrongly presented screws are brought into alignment with the internal thread.

Reduced wastage

The innovative design of NAVITIGHT® screws effectively prevents damage to the internal thread.

Process cost savings

The thread is preserved. This significantly reduces rework costs or time-consuming repairs.

All-purpose use

Ergonomic design for an optimum screw fastening angle during manual assembly. There are many benefits for automatic screw fastening too.

Detailed description


Self-aligning thread

Misalignment when a screw is inserted can often be a problem, especially in cramped conditions. Damage to the internal thread caused by jamming can lead to manufacturing stoppages and to substantial rework costs in some cases. To eliminate this source of error right at the assembly stage, the major diameter of the screw tip is smaller than the minor diameter of the female thread. As the thread pitch remains constant, the screw is automatically brought into alignment with the internal thread. This prevents any damage as the screw is tightened.
