Position grommet on die with barrel facing up, position material over grommet barrel, and
place the washer over grommet barrel.
When installing a flat grommet by the hand-held method, ensure the
grommet barrel and washer are aligned to preclude off-center
setting of the grommet.
Using a punch and rawhide mallet or other non-steel impact device, spread grommet barrel
by hammering until barrel collar is rolled down smooth on washer. If grommet barrel splits
during hammering process, remove and replace damaged grommet with a serviceable item
from stock, repeating procedures in paragraph b., above.
Check seating of grommet. If grommet can be turned by hand, repeat step (5) until
grommet is firmly seated.
Install appropriate chuck or die in hand-operated press and secure locking screws with hex
wrench, or screwdriver.
