RND light – round rivet nut for extremely high torques, light and space-efficient

The RND light is an addition to the RND standard. It is offered from M5 to M12 in various finishes.

Application area

  • These rivet nuts can be universally used for component thicknesses from 0.6 to 3.0 mm and tensile strengths of up to 1200 MPa
  • Suitable for a wide range of high dynamic, static and impact load conditions
  • Suitable for use where threaded fittings need to be resistant to high axial forces
  • Also suitable for the accommodation of lateral forces
  • Can be used for aluminium
  • Suitable for use with surface-treated, galvanised or painted components
  • Optimised in terms of weight and costs as compared to the RND (standard)

Technical characteristics

  • Thread sizes: M5 to M12
  • FK 8 (standard)
  • Resistance to corrosion in accordance with the customer´s requirements
  • No component material thinning during riveting process
  • No adverse effects on the joint or function of the thread; no damage due to weld spatters
  • High resistance to twist and ejection forces, even for thin sheet metals
  • Water-tight and gas-tight in reference to the requirements demanded by the automotive sector and dependent on the quality of the component material
  • Nut positioning tolerance ranges can be halved as compared to welding methods
  • Straightforward, in-process and non-destructive quality testing possible by worker instead of elaborate destructive tests

Can withstand high loads on both sides

Processing steps

  • Prepare hole
  • Position component above die
  • The support fastener is pushed through the component material by means of axial motion
  • The specific geometry of the die is used to form the rivet shaft around the hole of the component material so as to result in a form-fitting and friction-locking connection.
