INSTALLATION AND MATERIAL SPECIFICATIONS
Installation Specifications Material Specifications
Anchor Shield Zamac Alloy
Cone Zamac Alloy
Anchor Component Component Material
Drill a hole into the
base material to the
minimum depth
required. The
tolerances of
the drill bit used
should meet the
requirements of
ANSI Standard
B212.15. Do not
expand the anchor
prior to installation.
Do not over drill the hole unless the application
calls for a subset anchor.
Insert anchor into
the hole, threaded
cone end first
until the outer
sleeve is flush with
the surface of the
base material.
Position fixture,
then insert
screw or bolt
and tighten.
For maximum
expansion, the
upper cone should
protrude slightly
before setting.
The bolt must
engage a
minimum of
2/3 of the
anchor threads.
