a. Wedge Concrete Anchors

A Wedge concrete anchor owns the wedges open and expands up to 1/16” at the anchor’s base. when the bolt is tightened.

This is a male concrete anchor which is employed for attaching to the base of concrete with the usefulness of a nut and washer.

Also, wedge concrete anchors are commonly employed because it is straightforward to insert, corrosion-resistant, and among the strongest concrete anchors.

It is actually a stud made of two connected pieces one piece is threaded at the top end and the other end consists of a method that contains a wedge and clip that is expanded between the stud and the wall of the hole in the concrete.

The wedge concrete anchors are typically the best choice for heavy shear and load applications. Furthermore, heavier-duty seismic wedge anchors are employed in locations visited by seismic activities.


A few points that need to keep in mind about wedge anchors:

The holes drilled into the concrete for a wedge anchor should be equivalent to the diameter of the anchor.

Also, it is employed for solid concrete only not for stone, mortar, brick, etc.

b. Drop-in Anchors

Wedge anchors and drop-in anchors are sometimes confusing because they develop similarly, drop-in anchors are female anchors that are positioned in a pre-drilled hole.

The expander plug at the anchor’s base is specified employing a setting tool which is basically a steel rod with one end necked down.

The necked-down part of the tool is attached to the drop-in anchor and tapped with a hammer until the lip of the anchor satisfies the lip of the setting tool.

Like the wedge anchor, drop-in anchors are planned for solid concrete only and can’t be employed actually in brick, block, mortar, or stone.


Drop-in Anchors



c. Double Expansion Shield Anchors

Double expansion shield anchors deliver a powerful, incredible method to confirm almost any material, including Inconel sheets.

They develop when kept in a dug hole in the material being fastened, which makes an extremely tight grip against pressure and slackening.

This creates them perfect for materials such as Inconel sheets because they require an additional durable fastener that can remain in place even with a lot of automated force on them.

Double Expansion Sheild Anchors are viewed as the best anchor solution obtainable when it comes to challenging materials like Inconel sheets.

g. Strike Anchor Lag Anchor

Strike anchors are male fasteners and it is employed to hook lightweight installation 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 completing the essential hold within the hole.

The hole diameter to be drilled for the strike anchors are the same diameter as that of the anchor to be used.

Strike anchors enable long runs of fixtures to be quickly installed but once placed they are not removable.


Strike Anchor Lag Anchor


h. Tapcon Concrete Anchor

Tapcon Concrete Anchors are one of the best when it is about to fasten materials to concrete.

These anchors employ developed manufacturing methods to make a powerful and dependable grip.

With its special thread design and intuitive establishing process, Tapcon concrete anchors are excellent for a variety of applications, containing construction, remodeling, and DIY projects.

Whether you’re securing a shelving entity to a concrete wall or mounting a TV bracket, Tapcon anchors produce it straightforwardly to acquire a secure and enduring hold.

i. Kaptoggle Hollow Wall Anchors

Kaptoggle anchors deliver a protected and dependable way to scale items onto hollow walls. Constructed from Inconel steel, these specialty anchors are developed to be inserted through the wall where they thread and develop behind it to deliver a tension hold that won’t stretch out.

For more dependability, the Inconel sheets make an extremely powerful hold that survives most traditional drywall mounting choices.

Kaptoggle anchors can be employed to hang shelves, clocks, pictures, bathroom accessories, and considerably more in any setting with hollow walls, providing each item remains securely in place for years.

j. Lag Shield Concrete Anchors

Lag concrete anchors are female anchors and they include a sleeve that is tapered and ribbed in form and texture.

The lag concrete anchor sleeves are created of a zinc alloy and the sleeves are simple in nature.

These sleeves are positioned 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 trimmed the threaded portion of the anchor.

That lag concrete anchors are packed inside the exterior wall of the base materials. Relying upon the diameter of a bolt that is assumed to go inside the screw then the lag concrete anchor is prepared according to their implanted length.

Typically, the longer lag anchors are holding a more powerful and good grip that maintains the base material.

Another side the lag concrete anchor is small then it is dense and hard.

k. Machine Screw Anchors

Machine screw angle anchors can be employed to ensure Inconel sheet structures due to their superior load-bearing capability.

Made from heavy-duty materials like carbon steel and stainless steel, these anchors are also admiringly corrosion unsusceptible, so they stay sturdy and long-lasting in outdoor surroundings. The threading of the screws permits for a secure fastening and assists in controlling the side rotation of the Inconel sheet.

In addition to making a sturdy structure, machine screw angle anchors are incredibly easy to establish, needing only a few easy actions.

With their versatility and reliability, machine screw angle anchors create an outstanding option for building Inconel sheet structures.

l. Concrete Sleeve Anchors

Concrete Sleeve Anchors are male fasteners. It consists of a threaded bolt covered by an expander sleeve at the top end and a washer and nut at the next end.

The Sleeves anchors are threaded through the installation and into the pre-drilled hole in the concrete, stone, brick, and mortar.

The act of turning the bolt on the nut tightens the bolt up through the sleeves pushing the sleeve to flare out up to 1/8”.


Concrete Sleeve Anchors



m. Masonry Screws

Masonry screws are an ideal alternative for securing Inconel sheets jointly. Their excellent corrosion resistance ensures that the task will stay intact no matter the circumstances it is open to.

In addition to their widespread durability, masonry screws are made difficult to actually hold onto Inconel sheets and maintain them secured in place.
