Anchor sleeves: Buyer’s guide

Using anchor sleeves for masonry anchoring is an easy-to-use, quick and flexible process. A wide range of materials can be used with them, as well as applications exposed to seismic loads. Fasteners create a strong connection between the bolt and the base material when they are tightened, which is capable of distributing the weight of the load.

The purpose of this guide is to show you how anchor sleeves work, what are the common sleeve anchor sizes, which type of anchor sleeves, like resin anchor sleeves or concrete anchor sleeves are suitable for you and how they are applied as well as how you can use them effectively to choose the right one for your application.

What are chemical anchor sleeves and how do sleeve anchors work

In order for your project to be effective and have a long life span, you must choose the right fixing. You should choose the right anchor sleeves for your project, as they are often permanent fixtures.

Anchor sleeves have several uses. Typical applications include fixing radiators in the home, as well as securing the joists of decking. They can also be used for heavy-duty work such as securing a garage door.

Concrete, brick, and block can all be used as base materials for these anchor bolts. For dry indoor environments, stainless steel sleeve anchors are more suitable than zinc plated anchors. The design of the fixing will ultimately determine where they can be used.

Zinc plating is rarely able to withstand prolonged outdoor exposure, while stainless steel is anti-corrosive, even in marine environments. Stainless steel is ideally suited for indoor use away from the elements.

Anchor sleeves come in different types, which makes their uses more diverse. Additionally, these fastenings can be used to attach light fixtures to concrete walls or ceilings, attach door frames, and secure electric junction boxes.

Sleeve anchor installation: Steps to follow

Friction ensures a strong bond between concrete and the fixing. The strength of the project depends on the correct installation of the sleeve anchor.

For a solid, secure bond, make sure you follow our installation guide.

Step 1: Drilling a hole

Locate the anchor holes of the material on the concrete and position the material where you want to anchor it. It may be possible to leave the product in place when drilling the holes if there is sufficient clearance. In this case, the product can be positioned more precisely. Then, drill the bolt holes in concrete using a hammer drill.

It is important to measure the hole’s size. You should drill holes with a diameter that corresponds to the anchor you plan to use, plus 1/2′′ to 1′′ deeper than the expected depth of the anchor. From beneath the nut, the length of the anchor sleeves are measured.

Step 2: Installing the anchor sleeve

Pre-assembled fixings are available. In order to insert the anchor correctly, the nut must be in line with the top of the thread. This will prevent the threads from cracking. Insert the anchor body into the base material through the product hole. The nut and washer should be flush with the fixing after tapping the anchor with a hammer. The nut should be tightened by hand first. Sleeve anchors cannot be removed once they are installed, so you need to hand tighten them to ensure you’re happy with the placement.

Step 3: Decide the spacing

What is the number of  anchor sleeves you will need? The holding power of a fixation can actually be diminished if the fixings are too closely spaced. A minimum of ten anchor diameters should separate them, and they should not be closer to an unsupported edge than five diameters.

In cases of severe vibrations or sudden impacts, increase the spacing between fasteners to reduce the interaction of forces created within the base material.
