RIVKLE Elastic
The Principle
The RIVKLE Elastic is an easily fitted fastener,
where components subject to vibration are not only
securely and tightly screwed together from one
side of the workpiece, but at the same timeoscillation is
dampened, along with any vibrationary
noise. In addition, an electrically insulated screw
fastening is created between two components.
The fastening consists of a metal threaded insert
captured within a bearing component made of
thermoplastic elastomer. The brass insert is coated
in EPDM-X+PP. On installation, the RIVKLE
Elastic is inserted into a pilot hole drilled or pierced
within the holding component. Clamping nodules
beneath the external flange retain the fastener in its
unset state, preventing loss during assembly. As
the threaded portion of the female insert is at the
base of the elastomer fastener, tightening a mating
screw draws back the fastener to form a bead
which bears against the blind side of the
component.
If component A is made of steel, with a pilot hole to
DIN ISO 273, RIVKLE Elastic without washer
should be used. RIVKLE Elastic with washer is
preferred for components made of plastic,
aluminium or steel with an oblong hole. A starting
torque can be stipulated for the screw fastening
according to the pressure resistance of the
fastening component.
Technical DataThe starting torque MA is dependent on the
component material and the quality of the screw.
Axial load F should be tested for each application
with all parameters being synchronised.

mounted from one side of the workpiece
absorbs vibrations thereby reducing noise
insulates against heat and electricity
a force-locked screw fastening, producing screw
