Wedge anchors are mechanical devices to be installed in a solid concrete base only. They are one of the types of anchor bolts. Wedge anchors cannot be used in other base materials like cement or brick. They are holed in the concrete permanently and drilling into the concretes creates an exceptional holding capacity. The name wedge anchor is the generic name, but they may be called with other names such as kwik bolts. Once this is holed inside, the nut is rotated clockwise which pulls the action body up and slides down the expansion clip creating a tight bond between the anchor body and the concrete material. They are used for various concrete applications, but below down are mentioned applications of wedge anchors.

Why are wedge anchors only used for concrete material?The wedge anchors are made up of such a structure wherein they need solid contact with the material internally. The wedge anchors could not function in materials that are hollow or absorptive from the inside. An example such as a brick it is hollow from the inside and does not have good holding capacity.What are the problems which could take place if they are installed in other base materials?
  • The installation of anchors won’t be possible. This will result in no holding values
  • It would get difficult to remove the anchor once drilled inside, which would ultimately destroy the material.
  • Other base materials would get damaged while the installation process
  • If the material is hollow and absorptive the wedge anchor will spin the whole.
  • Working/ functioning of wedge anchor
Firstly, the hole is drilled according to the required diameter and length of the wedge anchor. Then the wedge anchor is installed into the pre-drilled hole of concrete.Now the wedge anchor is to be installed from the side of the expansion clip. After this, the nut is tightened clockwise.This action pulls the anchor body up, which slides the expansion clip down the cone-shaped working end of the wedge anchor. The clip is then expanded and wedges between the anchor body and the concrete.What are the various components/parts of the wedge anchor?The wedge anchor is majorly consisting of 4 major parts mentioned belowAnchor bodyThis could be made up of various materials but usually, stainless steel or carbon steel is used to make an anchor body. It is threaded on one end for a portion of its length while the diameter is necked down and cone-shaped tapering up to the nominal diameter at its other end.Expansion clipIt is a part of the anchor which is permanently installed inside this is made up of carbon steel and stainless steel.NutsIt is a very important part of a wedge anchor it is used to fix various parts with each other. It is made of stainless steel, they are available in various shapes but usually, hexagonal nuts are used.WasherIt is used for distributing the load of a threaded fastener. It is a thin plate with a hole, which is made up of carbon steel or stainless steel.What are the various types of wedge anchors based on the material used?Stainless steel wedge anchorsThe wedge anchors here are made up of stainless steel, they are preferred as one of the most durable materials available. It is strong compared to other materials available. They are a bit expensive compared to the other type of materials. Stainless steel is made up of an alloy of iron, chromium, and nickel. They are available in two types
  • 304 stainless steel
It is made up of an alloy of chromium and nickel they may also consist few percentages of manganese or carbon. They are used in a humid atmosphere. They are anti-corrosive and durable. They are cheaper than the 316 stainless steel wedge anchors.
  • 316 stainless steel
Stainless steel is made of chromium, nickel, molybdenum, and carbon they are the strongest and most durable types. They could be used in extreme conditions. They are anti-rust in nature. The only drawback is they are not cost-effective and very expensive. They could be used under the seaways in various industries.Galvanized wedge anchorsHere the anchor is made up of galvanized steel which means the metal gets a layer of zinc on its outer surface. The process of galvanization protects metal from getting corroded. They could be either being hot-dipped galvanized wedge anchors. Wherein they are dipped in zinc with the presence of high temperature or they could be electrically by the process of electrolysis. Yet they aren’t suitable for extreme conditions it may lead to the corrosion of the anchors. They are generally used indoors or maybe outdoors with low humidity. Accept concrete the galvanized wed anchors could also be used in lumber.Zinc plated wedge anchorsThey are the most common type of wedge anchor they are made up of zinc. They are suitable for light fixtures. They are recommended for indoors mostly or they could be used outdoors wherein they have a dry atmosphere. They are very less resistant to corrosion which makes them unfit for the humid atmosphere. They could be only used in concrete and they are not used in other base materials.

What are the various types of wedge anchors based on anchor threading?Fully threaded wedge anchorsThe threading on such anchors is equivalent to the length of the entire rod. They are very commonly used as they are comparatively more flexible. Their length could be easily adjusted or leveled according to the requirements.Partially threaded wedge anchorsThe threading on such anchors is 1/3 or 2/3 of the total length of the steel rod. They have many restrictions, they cannot be installed if the hole is not drilled according to the diameter and length of the wedge anchor.Full-bodied wedge anchorsThey are one of the types of partially threaded wedge anchors. But they are highly durable and stable as they are made up of a special type of steel. They are more effective than the fully threaded and partially threaded wedge anchors.What are the advantages of wedge anchors?Easy to have functionedWedge anchors do not have any complex functioning they are to be installed in a pre-drilled hole. They are only required to install in pre-dilled whole wherein they need to be assembled to start the function. Secondly, the parts of anchors could be easily fixed with each other with the help of a nut.
  • Wide variety of choices
Wedge anchors are available in various choices which makes it consumer-friendly. They are available in various materials such as stainless steel, zinc, and galvanized. They could be also bifurcated based on their thread end such as fully threaded or full-bodied.Highly durable and reliableThe wedge anchors are usually made from stainless steel or carbon steel which makes Them highly durable. They could also be used in an extreme situation wherein the atmosphere has high temperature and high humidity present in it. Thus they are considered to be effective in the long run.Anti-rustThe wedge anchors are majorly corrosion resistive which means they are free from rusting which proves to be one of the biggest advantages. They tend to have a long life and are more functional than other concrete-type anchors.What are the disadvantages of wedge anchors?The removal or repair of an anchor is very difficultOnce the wedge anchors are installed in pre-drilled holes the removal of the anchors is not possible. Thus the forced removal may lead to damage or destruction to the base material.Limitation in the usage of wedge anchorsWedge anchors could not be used in all the base material. Their use is limited to a few materials only. They could be only used in concrete and in some cases, they are used in lumber. Other than these they have not used in base materials such as brick.
