A traditional anchor stud is typically used for fastening structural or non-structural elements to the concrete. It is threaded on one end, while the other end is necked down with a permanently attached clip. In the construction industry, the use of anchor studs is prevalent since they are simple to use and have excellent holding values. Aside from their excellent usability and reliability, these studs also come in different materials and key dimensions.

While they can bring a lot to construction and other related projects, there are some situations where a different type of hardware device is needed. Chemical anchor studs, also known as resin anchors, can offer excellent fastening functionality through a specialised fastening technique. This technique lets a chemical anchor stud bond with a substrate that is injected with a special resin into its hole.

Principles of Chemical Anchor Studs

Some common problems that exist with the use of traditional anchor studs in a specific structure are splitting and cracking. These issues arise when anchors are applied toward the edge of the material, which consequently affects the strength and efficiency of the anchor stud and the material.

What makes chemical anchor studs different from the traditional ones is that they are not fastened in a conventional method. They do not hold themselves against the surface of the substrate, which significantly reduces the chance of splitting and cracking issues. Instead, these anchor studs are bonded with a substrate that has a special chemical resin on it to keep it in place. This special type of resin cures around the anchor stud and strongly secures the fastener in place.

Uses of Chemical Anchor Studs 

Chemical anchor studs are usually used in materials made from concrete or brick. Additionally, these studs can also be used on materials and surfaces that may already split or crack when fastened with sleeve anchors and screw threads. Delicate masonry is one of the most popular applications that can benefit the most with chemical anchor studs.

The uses of chemical anchor studs also extend to different positions. Their dependence on special resin helps them work in a downward or horizontal position. They can even be used underwater.

Chemical Anchor Studs Application

One thing that you should do when applying chemical anchor studs is to make appropriate holes. This step is crucial so that your fasteners can provide you your needed maximum strength. Knowing the depth of your drill is also important so that your anchor stud can swiftly be installed without any compromises. You must also remember that drilling straight can be a negative thing for your chemical resin as it might just flow straight out.

Drilled holes that have voids must be applied with resin injection anchor sleeves for an appropriate resin flow control. The removal of loose material from the hole must also be done through blowing air into the hole or brushing them with a resin hole brush.

Once the holes are clean, you can now inject the resin into the hole through a proper dispensing tool. If the hole from the bottom is now closely filled up with resin, then you must now slowly insert the anchor stud into it. You can twist it momentarily to break any air bubbles that may have accumulated on your resin application and wipe off any extra resin that may come out. If the stud is fully inserted, you must allow the whole thing to cure for a specific amount of time for greater results.
