Decoupling

RIVKLE® Elastic

Noise and vibration-decoupling fastening. With RIVKLE® Elastic blind rivet nuts for thin-walled components.

For decoupling fasteners

RIVKLE® Elastic is the innovative solution for fastening load-bearing thread bodies to thin-walled components while providing vibration and noise damping effects.

The removable blind rivet fastener consists of a threaded metal insert coated with an elastomer or thermoplastic elastomer.


Method / principle

The RIVKLE® Elastic is inserted into the pilot hole from one side of the carrier component. The blind rivet is held in place by clamping nodules until it is securely fastened. Since the metal body is only connected to the elastomer in the lower area, a bulge forms and touches the component to be fastened on the rear side, when a screw is screwed in. This is a reversible rivet joint.

Applications

RIVKLE® Elastic is used in the automotive sector for mounting such things as engine spoilers, filters, compressors and side components for motorbikes. RIVKLE® Elastic is also applied in general industry, e.g. as a fastening element in electronics and for agricultural machinery.

Product benefits

There are many good reasons for using our products.

Strength and options.
Point by point.

One-side installation

Simple blind installation. Often the only solution for hollow bodies, housing or components with access only from one side.

Easy installation

Setting takes place during the screwing process. When the screw is tightened, a bulge forms on the rear side of the component to be fastened.

Insulation

Elastomer and thermoplastic elastomers provide electrical and thermal insulation.

Tolerance compensation - stress equalisation

Whether extreme thermal expansion or high dynamics – RIVKLE® Elastic fastens components reliably and securely.

Detailed description

 

System versions

The standard RIVKLE® Elastic is available in two basic versions and four sizes – M 4, M 5, M 6 and M 8.
The standard versions are available in different shank lengths, shank diameters, metal inserts, thread types, thread diameters, thread lengths, materials and colours. The metal inserts are also available in various materials and surface finishes.


RIVKLE® Elastic with washer

If the component to be fastened is made of steel and has a pilot hole to DIN ISO 273 standard, RIVKLE® Elastic can be used without a washer.


RIVKLE® Elastic without washer

If the component is made of plastic, aluminium or steel and has a slotted hole, the RIVKLE® Elastic with washer should be used.

Material properties of the body

 

Thermoplastic elastomers

A thermoplastic elastomer is used with the standard version of the RIVKLE® Elastic.
TPE-V has the following characteristics:

TPE-V

  • Good mechanical properties in the temperature range – 40 °C to + 120 °C
  • Good media resistance
 

Elastomers

The RIVKLE® Elastic with elastomer body is divided into two groups: EPDM and VMQ.
Other types of elastomer such as AEM, ECO can also be applied.

EPDM

  • Very good compression set rating
  • Good chemical resistance
  • Good resistance to mineral oils and greases
  • Continuous operating temperature up to approx. + 130 °C

VMQ

  • Very good thermal resistance from approx. – 80 °C up to + 200 °C
  • Excellent ageing resistance
  • High resistance to oil and grease
