Round press-in nut for single-stage processing

Thread sizes: M6 to M8

Application area

  • These press-in pierce nuts can be universally used for component thicknesses from 0.6 to 2.0 mm and tensile strengths of up to 800 MPa
  • Suitable for extremely high dynamic and static axial and shear loads
  • Can be used for aluminium or other materials
  • Suitable for use with surface-treated, galvanised or painted components
  • High resistance to twist and ejection forces for thin sheet metals

Technical characteristics

  • Thread sizes: M5 to M10
  • FK 8 (standard)
  • Self-piercing, single-stage placement (no hole preparation required)
  • Resistance to corrosion in accordance with the customerĀ“s requirements
  • 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 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

Processing steps

  • Position component above die
  • A hole is punched for the nut by means of axial motion and with the aid of a preceding hole punch
  • The specific geometry of the die is used to form from the component material the area around the inside of the nut so as to result in a form-fitting and friction-locking connection. There is no deformation of the nut
