Installation dimensions according to the technical data sheet

Form A denotes a round closing head after riveting; form B denotes a conical closing head after riveting. These are two ways of forming the free end of the rivet. They do not change the factory-formed round head. The s values apply separately to each form, rather than to a common thickness range.

  • Installation hole d7: 3,1 mm
  • Hole tolerance d7: H12
  • Thickness of joined components s — form A: 14 mm
  • Thickness of joined components s — form B: 16 mm

  • Closing head height k1 — form A: 1,8 mm
  • Closing head height k2 — form B: Approximately 1,3 mm
  • Depth t1 — form B: 1,3 mm

Selecting the rivet and riveting method requires consideration of component thickness, hole preparation and the tools used. Tolerance designations from the data sheet are given; no unconfirmed numerical length deviations have been added.
