How to Install Sleeve Anchors in Concrete?

There are several different types of sleeve anchors, and they are each designed to fit a specific application. In some cases, sleeve anchors are also used for structural fastening in concrete. Cast-in-place bolts, for instance, have a special head that is designed to securely insert into concrete, but without a thread. This means that they can be used with other objects, such as anchors.

In order to install sleeve anchors, you must clean the insertion hole. The hole should be drilled at least a half-inch deeper than the expected embedment, depending on the material and thickness of the fixture. Then, use a wire brush, vacuum, or compressed air tool to remove any debris or particles from the insertion area. Once the hole is clean, insert the sleeve anchor through the fixture and base material. To ensure proper holding value, tighten the anchor to finger-tight.

Another type of sleeve anchors is the nut drive sleeve. These are ideal for use in masonry projects, as they are simple to install. They are most often used in brick or block, but are also compatible with concrete. While sleeve anchors are not as strong as wedge anchors, they can still work effectively for light to medium-weight holding applications. Nut drive sleeve anchors are often used for concrete projects.

A nut driven sleeve anchor requires drilling a hole in the concrete to install. The nut and washer are then placed on the exposed threading of the anchor. As the anchor is inserted into the concrete, the nut and washer expand in the sleeve, making it easier for it to be pulled out without cracking. Unlike a nut-driven sleeve anchor, sleeve anchors can be used for flush mount installations, whereas the "Flat head" type is used for embedment.
