dimensions must be identical with originally used rivets and material of rivets must fulfill the
same material characteristics.
15.3.2
Riveting procedure
(a) Fit the parts being connected and drill them together. Hole diameter must be by
0.1 mm (
0.004 in
) bigger than rivet shank diameter.
NOTE:
When drilling, fix by clamps or clecos mutual position of assembled parts.
Holes of higher diameters pre-drill with a drill bit of smaller diameter and then
redrill them to the final size.
(b) Disassemble the parts and deburr the holes.
NOTE:
For sunken rivets perform conical countersinking of the rivet head by 5°
smaller apex angle (e.g. the head with angle of 100° will have countersinking
of 95°±1°). After countersinking, the cylindrical part of hole with min. length of
0.3 mm (
0.012 in
) must remain in material. Countersinking must be performed
