High Integrated (HI) rectangular nut

Self-piercing HI-type nuts from PROFIL are fixed in place in a single process step. A high clamping capacity in the metal is what sets this type of pierced-in nut apart from other products. One application area for this type of rivet nut is thin sheet metals used in body manufacture with moderate strength requirements. As a systems provider, PROFIL can offer both suitable rivet nuts along with the corresponding processing method. An excellent cost/performance ratio is ensured by using this system.

Application area

  • Thread sizes: M6 to M8
  • Self-piercing, single-stage placement (no hole preparation required)
  • FK 8 (standard)
  • 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
  • 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

Technical characteristics

  • These pierce nuts can be universally used for component thicknesses from 0.7 to 2.0 mm and tensile strengths of up to 800 MPa
  • Suitable for a wide range of high dynamic load conditions
  • High resistance to twist and ejection forces for thin sheet metals
  • Can be used for aluminium
  • Suitable for use with surface-treated, galvanised or painted components

Processing steps

  • 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 from the component material the nut shaft area so as to result in a form-fitting and friction-locking connection. There is no deformation of the nut
