5 Uses for Sleeve Anchors
Sleeve anchors feature a steel sleeve on the shank and are split at the bottom, which expands when used. There are many uses to a sleeve anchor, but are commonly used in brick, concrete, block or brick base material and mortar. Concrete sleeve anchors are available in hex, flat or round head configurations, each with its own uses.
A sleeve anchor is more suitable if you are working with soft concrete. It will easily insert into a hole and it will not crack the concrete during installation. A sleeve anchor also reduces concrete stress while providing a 360 degree hole contact on large areas.
Sleeve anchors are also used in mortar joints between blocks or bricks. Since sleeve anchors have more bearing surface, it will not affect the position of the blocks or bricks.
A sleeve anchor is a great choice if you are planning to fasten a light fixture onto concrete walls or ceilings. If you are installing light fixtures outdoors, it is advisable to use stainless steel anchors to prevent rust and corrosion. On the other hand, zinc-plated sleeve anchors are best for non-caustic environments or indoor applications.
A type of sleeve anchor is also used for attaching door frames to concrete, brick or mortar walls. A flat headed sleeve anchor is commonly used for this type of application. The anchor fastens the door frames to the structure of the building or the thresholds of the doorway.
Electric Junction Boxes
Another use for sleeve anchors is for the installation of electric junction boxes. A round headed sleeve anchor is more suitable for this type of application since it provides more space for wires and does not snag the wires being placed in the junction box.
