NOTE
Open end rivets may be used only where moisture and dirt intrusion will not effect the shelter.
(1) Installation. (Figure 5-2).
NOTE
When installing new rivets in the same location as a rivet that has been removed, if diameter
of hole in structure has been enlarged during removal of rivet, use next larger diameter rivet
for replacement. Clean rivets with solvent before installing.
(a)
Determine type, size, and grip range of rivet to be used. Grip length equals the combined thickness of the
materials being riveted together. Grip range of the rivet must encompass the grip length.
WARNING
Drilling creates metal chips which may enter eyes and cause serious injury. Eye protection is
required.
CAUTION
Make sure drill bit has a stop attached which will prohibit the drill from exceeding a depth of
one inch.
NOTE
Drill hole size must match the size of the rivet being used. Quantities of sheets may be drilled
at the same time when held together with sheet fasteners.
(b)
Drill hole in structure.
(c)
Remove all metal chips and burrs from drilled holes.
(d)
If flush head rivet is being installed, countersink hole using a 100-degree or 120-degree machine countersink.
(e)
Coat all rivet bodies with fiber filled polyester resin (Item 10, Appendix E) before installing.
(f)
Insert rivet in hole. Make sure sheets are held tightly together before upsetting or pulling rivet.
(g)
Select proper pulling head for rivet being installed and install pulling head on rivet gun.
(h)
Insert stem of rivet into pulling head.
(i)
With pulling head parallel to axis of rivet, upset rivet. Exert firm pressure but do not bend or buckle metal
sheets. Stem will break off below rivet head surface. No trimming should be required.
(j)
Make sure riveted parts are not loose, rivet does not rotate, and rivet head is seated tightly against riveted
surface. If rivet is loose or improperly installed, remove the rivet and repeat steps (a) through (i).
