WITOL® Adjust

The adjustment element for maximum flexibility even after screwing

With the WITOL Adjust setting elements, you have maximum flexibility in assembling individual components. The pre-set WITOL Adjust is pre-mounted on your component or the car body using individual connection concepts. Subsequently, you can align your component at the installation location and screw it as usual.

In addition to radial compensation during the bolting process, WITOL Adjust adjustment elements offer the possibility of subsequently adjusting an end position axially – by manual adjustment. For this procedure, the screw connection does not have to be loosened again and therefore has no influence on the preload forces in the system. A self-locking thread geometry prevents unintentional adjustment of the components and requires no additional fixing after the end position has been reached.

Especially in complex installation situations, where several attachment parts meet, WITOL Adjust adjustment elements offer the optimal solution to bring the gap course to the perfect final dimension even after screwing. In addition, fine adjustment is possible, which cannot be achieved with classic fasteners:

  • Optimal gap progression even after bolting
  • Simplified assembly process even for complex installation situations
  • High precision with optimized cycle times
  • Manual adjustment without influencing the pretensioning forces

WITOL® Lightweight

Our solution for lightweight design

WITOL Lightweight are always used when weight is a particularly critical factor. They are ideally suited for use with defined pretensioning forces in assembly.

This lightweight design of the tolerance compensation systems offers decisive advantages for the optimized manufacturing process: Due to the product design, the fastening solutions are largely to completely made of high-strength and heat-resistant special plastics, which makes the weight even lighter compared to other materials and solutions. WITOL Lightweight can be equipped with individual shaping and integration of special functions according to customer requirements and thus be adapted exactly to your application.

  • Low weight
  • Made of high-strength and heat-resistant special plastics
  • Individually adaptable to the production process

WITOL® Connect

Innovative fastening solution for small installation space or for pre-positioning

The WITOL Connect is a tolerance compensation element that is used for particularly small installation space requirements. The central product component is a center collar bolt with a thread on both sides (right/left) which is screwed into the threaded insert with the Liks thread. This insert can then be used in a luminaire module, for example. The WITOL Connect is driven by tightening a nut and automatically compensates for distances between components.

Another application of WITOL Connect is the pre-positioning of larger modules. For this purpose, previously screwed-in bolts are pushed into the WITOL Connect locking inserts and locked in the desired position. The fact that the insertion forces are significantly lower than the necessary extraction forces significantly simplifies handling during assembly.

WITOL Surface

WITOL® Surface

Highly integrative fastening solutions with maximum process reliability

If a constant and flat distance between the surface and the screw-on part is required, the highly integrative WITOL Surface is used. This is made possible by the innovative relocation of the functional area to the interior of the component structure.

The WITOL Surface proves to be extremely process-safe over the complete range of application and is characterized by easy handling. Depending on the application, it may be necessary to keep the joining forces of the WITOL as low as possible for ergonomic reasons. This also enables overhead and one-hand assembly in compliance with occupational health and safety regulations.



Highly efficient and cost-optimized compensation element

For simple leveling – we have developed the WITOL Pure. The proven WITOL operating principle has been further simplified by reducing the number of components. The WITOL Pure is a cost-optimized compensating element made of plastic with an integrated steel nut and is used when components are to be positioned positively to each other. The flange nut used is a widely used and proven standard part and is therefore highly compatible.

The WITOL Pure is deliberately designed for the pure compensating function, which in turn increases the functional reliability. The use of plastic and the reduced number of components also result in a weight advantage.
