Advantages of SITEC®

Decoupling

Our SITEC® elements provide you with intelligent solutions that fasten while also reducing noise and vibrations.
Versatility

Choose the screw or plug that suits your mounting component from the various SITEC® fastener variants. You can also choose from different materials (e.g. for different temperature requirements).
Speed

Whichever SITEC® variant you choose, they are all quick and easy to assemble.

Method and principle

Approaches to vibration and noise reduction

Damping

One method for reducing vibrations and the resulting noise emissions is damping. During material-based damping, kinetic vibration energy is converted into thermal energy.

The principle of damping describes the reduction of an output quantity over time. This energy conversion process can be achieved with SITEC® fasteners using technical elastomers.

Isolation

Another method for reducing noise emissions is vibration isolation. Unlike damping, this does not involve conversion of energy to reduce the amplitude. Instead, the vibrations are detuned.

The principle behind this is that excitation is directly absorbed by an elastic fastener. The spring rate of the fastener is fine-tuned so that energy is transferred at a considerably reduced amplitude. This type of reduction is primarily employed for applications that generate high levels of vibration.

SITEC® product types

Discover our various fasteners for noise and vibration decoupling.

SITEC® Rivet
You can use this decoupling blind rivet nut to fasten a high-strength thread body to a thin-walled component with an additional vibration and noise decoupling effect.

Advantages

Vibration and noise decoupling

Thermal and electrical insulation

Load-bearing thread on thin-walled components

Adjustable parameters for a flexibility in design (material, connection solution)
SITEC® Pin
This solution consists of a plastic stud and a soft damping element. With two undercut geometries, this fastener smoothly fits into bore holes of different plate thicknesses without the use of a tool. Pressing down the stud establishes the fastening.

Advantages

Vibration and noise decoupling

Pre-assembly and final assembly

Fast, easy and secure

No tool required
SITEC® Clip
You can mount the SITEC® Clip quickly and easily on the panel geometry of your application. Two clips which are identical in design are clipped together, with an offset of 90°, in a round bore. The clips are then screwed to the mounted component.

Advantages

Pre-assembly and final assembly

Quick, easy and secure

No tool required

One fastening element for component thicknesses between 1 and 3 mm
SITEC® Spring
The purpose of the SITEC® Spring fastener is to isolate vibrations. The plug-plug-screw method is fast and easy to assemble. Tailored spring rigidity efficiently isolates the vibrations.

Advantages

Pre-assembly and final assembly

Quick, easy and secure

No tool required

Choice of materials to suit your temperature range
