A concrete anchor is a device that is used to secure objects to concrete surfaces. It is typically made of metal and is inserted into a drilled hole in the concrete. The anchor is then expanded or tightened to hold the object in place. Concrete anchors are used in a variety of applications, including construction, engineering, and home improvement projects.
They are commonly used to secure fixtures such as shelves, cabinets, and heavy machinery. There are different types of concrete anchors, including wedge anchors, sleeve anchors, and drop-in anchors, and the type of anchor used depends on the weight and type of object being secured, as well as the thickness of the concrete.
Types of Concrete Anchors
The following are the 10 best anchors for concrete,
Wedge Concrete Anchors
A Wedge concrete anchor is named after the wedges that open and expand up to 1/16” at the anchor’s base .when the bolt is tightened. This is a male concrete anchor which is used for fastening to the base of concrete with the use of a nut and washer.
Also, wedge concrete anchors are widely used because it is easy to insert, corrosion-resistant, and among the strongest concrete anchors. It is actually a stud constructed of two adjoined pieces one piece is threaded at the top end and the other end consists of a process that includes a wedge and clip that is expanded between the stud and the wall of the hole in the concrete.
Concrete Sleeve Anchor
Concrete Sleeve Anchors are male fasteners and It consists of a threaded bolt enveloped by an expander sleeve at the top end and a washer and nut at the other end. The Sleeves anchors are threaded through the fixture and into the pre-drilled hole in the concrete, stone, brick, and mortar.
The action of turning the bolt on the nut pulls the bolt up through the sleeves causing the sleeve to flare out up to 1/8”
Split Drive Concrete Anchors
These Split drive Concrete Anchors are got their holding power from the source of the resilient composition of the piece of one anchor itself. Also, this anchor is a male fastener with a split expanded base. Generally, it is suitable for light-duty tasks and suitable for block, concrete, brick, and stones base.
The most important things to keep in your mind when you install split drive, concrete anchors, The diameter of the anchor base is similar to the size of the drilled-out hole.
Stud Concrete Anchor
The sleeve concrete and wedge anchors are used as a tightened nut so that the anchors expand a lot against the hole or sides of the walls. The stud anchor also expands. But when you expand a stud anchor then you need hammering on the top portion of the anchor.
The expansion anchors are threading on the top end portion and the bottom end at that time drill holes have consisted of a vertical slit. At the bottom end of the stud anchor, there is a hole that sits on the tapered-shaped steel plug.

Lag Shield Concrete Anchors
Lag concrete anchors are female types of anchors and they have a sleeve that is tapered and ribbed in shape and texture. The lag concrete anchor sleeves are made of a zinc alloy material and the sleeves are plain in nature.
These sleeves are placed into the pre-making drill hole base that could be mortar, concrete, brick, stone, etc. These lag screws are goes inside and expand that zinc material sleeve, and then cut the threaded portion of the anchor.
That lag concrete anchors are pressed inside the exterior wall of the base materials. Depending upon the diameter of a bolt that is supposed to go inside the screw then the lag concrete anchor is designed according to their embedded length.
Self Drilling Concrete Anchor
A self-drilling concrete anchor is a name suggested as the anchor itself has its own teeth which means it is cutting holes into the concrete base by itself.
The top end of this anchor has internal threading and tapered-shaped steel plugs too. So that bolt can easily be screwed into it.
When you drill the shell on the tapered steel plug with the help of hammering, the bottom end of the shell will end up expanding while bearing the walls or side of the hole.
Drop-In Concrete Anchor
Sometimes confused with wedge anchors because they expand similarly, drop-in anchors are female anchors that are placed in a pre-drilled hole. The expander plug at the anchor’s base is set using a setting tool which is essentially a steel rod with one end necked down.
The necked-down portion of the tool is inserted into the drop-in anchor and tapped with a hammer until the lip of the anchor meets the lip of the setting tool. Like the wedge anchor, drop-in anchors are intended for solid concrete only and can’t be used effectively in brick, block, mortar, or stone.
Machine Screw Anchor
A machine Screw Anchor is a female anchor this type of fastener consists of a cylindrical base inserted into a pre-drilled hole in brick, mortar, stone, and concrete. These anchor screws are threaded through the fixture and into the base and hole, and the setting tools are used for turning the screw.
As the screw turns down into the base, it is expanding the base for securing the anchor in the hole, thereby fastening the fixture to the surface of the concrete. Each machine screw anchors have specific setting tools these are determined by the diameter of the machine screw anchor being used.
Strike Anchors
Strike anchors are male fasteners and it is used to join lightweight fixtures such as shelf brackets, conduit, and electrical boxes to solid concrete. The strike anchors are an impact expansion fastener consisting of a tabular body capped by a drive pin that is expanded from the tubular casing.
When the strike anchors are inserted into the pre-drilled hole then the head of its pins is driven further into the tube via hammer strikes, expanding the tube and creating the necessary hold within the hole.

It really stood out to me when you mentioned that anchor bolts are used to make a concrete structure more stable and secure. When purchasing anchoring bolts, I would imagine that it would be important to make sure that they are fabricated properly. Purchasing bolts from a reliable supplier would ensure that the bolts won’t fail when they are placed in a structure.
