Technology

Blind rivet nuts for vibration and noise-decoupling

RIVNUT® AV consists of a metal body with a metric thread (in most cases) and a wrapping of elastomer or thermoplastic elastomer.

This fastener is an innovative solution when a high-strength thread body must be fastened to a thin-walled component. It is additionally proven by its noise and vibration-decoupling properties.

When installed, RIVNUT® AV is inserted from one side into the mounting hole of the support part.
Until the final fastening, the clamping cams serve as a locking device.
Since the metal body (standard: brass) is only connected with the wrapping in the lower area, a bulge forms and touches the component to be fastened on the backside, when a screw is screwed in. This is a reversible rivet joint.
