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 size of rivnut being installed. 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 remove burrs from drilled holes.
(d) If a countersunk rivnut is being installed, countersink hole using a 100- degree machine countersink.
(e) Thread stem of appropriate pull-up stud into rivnut. Stud should protrude through open end rivnuts or be
1-1/2 threads from bottoming in closed end rivnuts.
