Tolerance Compensation with WITOL®

Access, Locking & Control Solutions
Create a solid and tension-free connection of two components with each other while compensating for manufacturing tolerances precisely – with WITOL® tolerance compensation fasteners.


WITOL® tolerance compensation systems compensate for component tolerances and inaccuracies quickly and precisely. Thanks to the simultaneous bolting and compensation process, they reduce assembly times significantly. In addition, the WITOL® system guarantees reproducible quality due to tolerance compensation independent of the worker.
WITOL® tolerance compensation systems were originally developed for the automotive industry, but they can be used wherever tolerances in the form of cavities must be compensated. Examples include the agriculture, railway, furniture or medical industries. Typical applications in vehicles include

The design of WITOL® fasteners enables precise and tension-free tolerance compensation between two components. A WITOL® consists of four elements:
Due to the rotation of the driven screw, tolerances are compensated directly in the bolting process – automatically and simultaneously. In this way, a WITOL® fastener creates a tension-free bolted joint in a process-safe manner.

WITOL® tolerance compensation systems allow a solid connection of two components with each other.
