7.2.3 Incorrect riveting
Gaps
Gaps along the entire circumference are not permissible. Gaps
along part of the circumference are permissible up to a gap width
of 0.04 mm.
You can use e.g. a tool insert from the riveting set to drive rivet in
further, but make sure that closing head and rivet head tolerances
are observed.
Rivet heads do not make full contact
Loose rivets are not permissible.
Partial gaps of up to 0.05 mm are permissible.
Swelling at riveted joint
During the riveting process the rivet material is pressed into the
gap, subjecting the rivet to bending stress.
Swelling of this kind is not permissible.
Swelling between riveted joints
Swelling must not exceed a gap width of 0.3 mm.
