Installation Instruction for Aggre-Gator
Step 1
Using the proper drill bit size, drill
a hole into the base material to
the required depth, ho, which is a
1/4-inch deeper than the minimum
embedment depth, h
nom
.
Step 2
Remove dust and debris from
the hole during drilling (e.g. dust
extractor) or following drilling
(e.g. suction, forced air) to
extract loose particles created
by drilling.
Step 3
Attach a Ultracon+ installation socket
tool for the selected anchor size to
a percussion drill and set the drill to
rotary only mode. Mount the screw
anchor head into the socket. For flat
head versions a bit tip must be used
with the socket tool.
Step 4
Place the point of the Aggre-Gator
through the fixture into the pre-drilled
hole and drive the anchor in one steady
continuous motion until it is fully seated
at the proper embedment. The driver
will automatically disengage from the
head of the Aggre-Gator.
