Tolerance compensation

FLEXITOL® tolerance compensation systems were developed to compensate tolerances with economical assembly solutions and thus ensure a safe sequence in series production.


Tolerance compensation systems FLEXITOL®

Not only in the automotive industry do production processes based on modular construction succeed.
Here, individual components are supplied to the assembler where they only have to be assembled.
To ensure flawless series production certain tolerances are assumed. The automatic tolerance compensation system FLEXITOL® provides a technically and economically optimised solution.


Tolerance compensation consists of an adjustment element and a fastening element.
The element is mounted into the receiving part. This can be realised in different ways (e. g. insertion and twisting or insertion and riveting).
The adjustment element is connected to a fastening element via a left-hand thread.
By screwing in the fastening element, the adjustment element is screwed out to the bearing face.
After that, the screw is screwed in again.
The compensation distance between receiving part and mounting part is thus compensated automatically and steplessly.

An animated representation of different installation procedures is provided on the right.


Your benefits

Product types

Currently, there are four FLEXITOL® types.

Different ranges of use present different requirements and require application-optimised tolerance compensation systems.

FLEXITOL® metal FLEXITOL® hybrid FLEXITOL® plastic
High stability ++ ++
Small installation space ++ ++
Large number of pieces + ++ ++
Low weight + ++
High temperature resistance ++ +
Mounting in plastic + ++
Recycling ++ + ++




The two-piece system is highly wear-resistant and can very well be retrofitted. Manual adjustment for re-adjustment is possible as well. The adjustment element can also be installed in solid material.

The fastening element is available in different designs.
Assembly is easy due to approved blind rivet technology.

FLEXITOL® hybrid

FLEXITOL® hybrid is a multi-component system mainly designed for use in large-scale production. Due to its modular construction, a variation of different inserted heights and tolerance compensation dimensions may easily be implemented.

To ensure high force transmission, the force transmitting components are made of metal. They are enclosed by a nut cage made of plastic.
Fastening is executed via the integrated blind rivet nut which can also be replaced with alternative connections (e. g. clips).

FLEXITOL® plastic

FLEXITOL® plastic for self-tapping screws

FLEXITOL® plastic

The two-piece FLEXITOL® plastic is screwed into the mounting hole of the component. Connection with the bayonet method is also possible. For this method, FLEXITOL® plastic has to be inserted into a keyhole-shaped receiving opening and locked with a quarter turn.

FLEXITOL® plastic

FLEXITOL® plastic for metric screws

The FLEXITOL® plastic consists of a plastic adjustment element and a plastic fastening element and is supplied as a pre-assembled assembly.
This assembly should be screwed into the mounting hole in the plastic receiving part. A bayonet variant offers another way to attach the basic element. The FLEXITOL® plastic is then inserted into a keyhole-shaped receiving opening and locked with a quarter turn. The subsequent installation is the same as for the self-tapping variant. Depending on the version, a self-tapping metal screw or a metric screw can be used as fastening screw.
