FLEXITOL®

This two-piece system is made entirely of metal and can therefore withstand high loads.

The minimal space required for installation in the separation gap makes this solution easy to install – and even retrofit – in an existing installation space. With the new generation of the FLEXITOL® Metal adjustment element, the system is significantly more durable and can furthermore be manufactured in a more cost-effective process.

Adjustment element

• For this new generation, the integrated friction function was transferred to the adjustment element interior.
• High-strength metal thread

Fastening element

• Compact system dimensions
• Blind rivet nut available in various versions
• Easy installation through established blind riveting technology

Multi-part system intended primarily for use in large-scale series production.

Due to the modular design, it is easy to modify the base heights and tolerance compensation dimensions.

To ensure maximum transmission forces, the transmitting components in this hybrid (plastic/metal) solution are made of metal. They are also enclosed by a nut cage made of plastic.
The integrated blind rivet nut is already present as a fastening thread.
 

The FLEXITOL® Plastic consists of an adjustment element and a fastening element made of plastic, and is supplied pre-assembled. It is easy to screw this assembly into the mounting hole of the plastic receiving component.

The bayonet variant offers an additional connection option for the base element. It allows the FLEXITOL® Plastic to be inserted into a keyhole-shaped opening and latched by rotating it by a quarter turn. The subsequent installation procedure is identical to the one for the self-tapping variant.
 

For "banjo screws", the function of the K' in K' thread is extremely important. The
K' in K' thread cuts its own pilot thread into the existing plastic bore hole.

Due to a resistance effect, the banjo screw can then only be screwed further in or out with a higher torque.

The FLEXITOL® Eco consists of a plastic cage with an in-moulded metal nut. The tolerance compensation takes place during installation when the plastic cage is compressed and automatically adapts to the degree of tolerance compensation required. No further adjustment process is necessary.
Due to the clip geometry in the bottom part of the plastic in-moulding, the fastener can also be pre-assembled and does not disassemble during transport.

The fastener can be used to fasten dash panels inside vehicle bodies, for example.

Thanks to the specially developed manual tolerance compensation system, you can align the assembled rear light with an ideal gap size.

Special solution for attaching the roof rail using a manual and an automatic tolerance compensation system

The thin metal of the roof panel makes it difficult to transmit any great force when attaching the roof rail. However, this problem is solved by a tolerance compensation specially developed by Böllhoff.
It transmits the forces to the underlying metal layers. Tolerances within the roof edge have no influence on the gap between the roof rail and the roof panel.
There are various systems available, which can be pre-installed either on the roof rail or in the car body.
