Technical Specifications — Sleeve Anchors
Before installing concrete sleeve anchors it is important to consider a number of technical specifications. These concrete
sleeve anchors come in four different head styles: acorn, hex, flat and round. Ultimate holding values, anchor length, and
minimum embedment will determine the size and type of sleeve anchor needed for a specific application. The sleeve
anchor can be installed in solid concrete, brick or block base material. The hole to be drilled in the base material
is equal to the diameter of the sleeve anchor being used.
Sleeve Anchor Length: The length of an anchor should equal minimum embedment, plus fixture, plus nut &
washer. The Sleeve anchor requires no maximum hole depth. The depth of the hole in the base material
should be at least the length of the sleeve anchor minus the thickness of the material being fastened. This
will provide some extra depth to accommodate a minor amount of concrete cuttings which may not be able
to be cleaned out of the hole.
Sleeve Anchor Spacing: The forces on a Sleeve Anchor are transferred to the material in which it is installed. If
the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the
holding power of the anchor. As a rule of thumb, the expansion anchor industry has established a minimum
standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from an
unsupported edge. When vibration or sudden impact are part of the load conditions, the spacing should
be increased.
