g. Monel rivets are used in special cases
for riveting high-nickel steel alloys and nickel
alloys. They may be used interchangeably
with stainless steel rivets as they are more eas-
ily driven. However, it is preferable to use
stainless steel rivets in stainless steel parts.
h. Copper rivets are used for riveting
copper alloys, leather, and other nonmetallic
materials. This rivet has only limited usage in
aircraft.
i. Hi-Shear rivets are sometimes used in
connections where the shearing loads are the
primary design consideration. Its use is re-
stricted to such connections. It should be
noted that Hi-Shear rivets are not to be used
for the installation of control surface hinges
and hinge brackets. Do not paint the rivets be-
fore assembly, even where dissimilar metals
are being joined. However, it is advisable to
touch up each end of the driven rivet with
primer to allow the later application of the
general airplane finish.
j. Blind rivets in the NASM20600
through NASM20603 series rivets and the me-
chanically-locked stem NAS 1398, 1399,
1738, and 1739 rivets sometimes may be sub-
stituted for solid rivets. They should not be
used where the looseness or failure of a few
rivets will impair the airworthiness of the air-
craft. Design allowable for blind rivets are
specified in MIL-HDBK-5. Specific structural
applications are outlined in NASM33522.
Nonstructural applications for such blind rivets
as NASM20604 and NASM20605 are con-
tained in NASM33557.
CAUTION: For sheet metal repairs to air-
frame, the use of blind rivets must be
authorized by the airframe manufacturer or
approved by a representative of the FAA.
