4. Care must be taken to assure rivet hole patterns are transferred accurately in the case where a part
with no holes is mated to one which already has rivet holes. Hole patterns may be transferred using one of the
Lay new part in place and use holes in mating part as a drill template. This requires new part be
underneath the mating part. Care must be taken not to distort original holes.
(b) Use removed part as a drill template by clamping the old and new parts together. This requires
parts nest flat and rivet flange be undistorted.
1. Loads are applied through a joint to fasteners that hold it together. These loads are applied to fasteners
in the form of shear loads or tension loads. If load is perpendicular to axis of fasteners, the fastener is loaded in
shear. The fastener is loaded in tension when load is along axis of fastener causing a pull on each end of
2. Rivets (1) are designed to be loaded in shear. Do not create any new joints during repairs which cause
rivets to be used in a tension application. Bolts (2) should be used for tension applications or substituted for
rivets in very high shear load applications.
