Tighten wood screws firmly, but do not overtighten.
Overtightening can damage the bolt, greatly reducing
its holding power.
WARNING
Concrete anchors are
not
intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material. If mounting to concrete wall
covered with plaster/drywall is unavoidable, plaster/
drywall (up to 5/8" thick) must be counterbored as
shown below. If plaster/drywall is thicker than 5/8",
custom fasteners must be supplied by installer.
