anchor through the material to be fastened
until the washer is flush with the surface
material.

Make sure that there are no electrical
wires in the area which the screws could
penetrate.
Always wear safety glasses and use other
necessary protective devices or apparel
when installing or working with anchors.
Anchors are not recommended for use in
lightweight masonry material such as
block or brick, or for use in new concrete
which has not had sufficient time to cure.
The use of core drills is not recommended
to drill holes for the anchors.
