COMPRESSION RIVETERS
For maximum power the combined length of the two rivet sets must be of the correct length.
Determine the correct lengths as follows:
Figure 1: When two cupped rivet sets are used:
The length of the body dimensions of the two rivet sets (A1, A2) should equal the closed height
dimension of the yoke (H) minus the total thickness of material being riveted together.
Figure 2: When one cupped set and one fl ush set are used:
The length of the body dimensions of the two rivet sets (A1, A2) should equal the closed height
dimension of the yoke H minus the total thickness of material being riveted (M) and the height of the
fi nished rivet head (Z) compressed by the fl ush set (A).
Figure 3: When two fl ush sets are used:
The length of the body dimensions of the two rivet sets (A1, A2) should equal the closed height
dimension of the yoke (H) minus the overall length of the rivet (L) after it is compressed.
If necessary, select rivet sets a little short and shim to the correct
length using spacer shims.
