A wedge anchor bolt is a type of anchor used in rigging and mooring applications. It works by wedging the boat’s bow into an object like a pier, rock or dock on either side. The purpose is to keep it stationary while others tie off ropes to secure the load. While they are relatively easy to use, there may be other types of anchors that would better suit your application
The “wedge anchor embedment depth” is a type of bolt that has been used for many years. It’s purpose is to provide more holding power than other types of bolts.
The expansion clip on Wedge Anchors grips the walls of embedment holes as the nut is tightened at the top. The collar extends and “wedges” between the material wall and bolt shank, effectively retaining the fixture in place.
What is a wedge anchor in this context?
The threaded anchor body, the expansion clip, a nut, and a washer make up a wedge anchor, which is a mechanical type expansion anchor. The greatest and most constant holding qualities of any mechanical type expansion anchor are provided by these anchors.
One could also wonder how deep wedge anchors should be. The hole should be bored at least 1/2″ deeper than the anchor’s penetration depth in the concrete. To enable the anchor to attain its minimum holding values, each diameter anchor has a Minimum Inclusion for installation.
Also, what is the function of an anchor bolt?
Anchor bolts hold structural and non-structural components to the concrete. An assembly of several components, such as anchor bolts (also known as fasteners), steel plates, and stiffeners, is used to form the connection. Anchor bolts transmit two kinds of forces: tension and shear forces.
What’s the best way to get rid of a wedge anchor?
There are three methods for removing wedge anchors from concrete:
- Simply pound the anchor into the concrete with a hammer if the hole underneath it is deep enough.
- Cut the anchor just above the surface using a saw or grinding wheel, then pound the rest flat with a hammer.

What makes a wedge anchor different from a sleeve anchor?
The wedge anchor, drop-in anchor and concrete strike anchor can only be used in solid concrete and have the highest & most consistent holding values in concrete. Concrete sleeve anchors can be used in concrete, brick or block but their holding values are less in terms of shear and pullout values.
Without drilling, how do you connect wood to concrete?
Here’s a quick and simple way to secure the wood to the concrete without having to use all those concrete anchors. A hammer drill, a 20-ounce hammer, and 16-diameter nails are required. In the hammer drill, insert a 1/4″ masonry drill bit that is 4 to 6 inches long. Drill through the concrete and through the wood.
For a 3/8 anchor, what size drill bit do you use?
Drill a 3/8″ hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212. 15. Drill the hole a 1/2″ deeper than the anchor will penetrate the concrete, making sure the Minimum Inclusion requirements of 1-1/2″ is met.
What’s the difference between an anchor bolt and a bolt that expands?
The force principle is different:
The anchor bolt permits a smooth screw to be strained by mechanical locking force; the expansion bolt, on the other hand, primarily causes friction by pushing and applying force.
What is the purpose of a wedge anchor?
Materials and equipment are anchored and secured to solid concrete masonry surfaces using Concrete Wedge Anchors. A mechanism towards the bottom of Concrete Wedge Anchor Bolts expands after fitted and “wedges” itself into the concrete. Wedge Anchors are only used in concrete and are put into drilled holes.
What is the definition of a wedge bolt?
The Wedge-Bolt anchor is a heavy-duty screw anchor with a completed hex head that comes in one piece. It’s easy to set up, recognize, and remove, and it’s also vibration-resistant. The Wedge- Bolt has a number of distinct characteristics and advantages that make it ideal for a wide range of applications in a variety of base materials.
What is the best way to secure bolts to concrete?
It’s difficult to top the speed and convenience of hammer-set anchors for anchoring anything reasonably light to concrete. Each anchor is made up of an unthreaded pin that is encased in a metal sleeve. Simply drill a hole in the concrete, place the fixture to be fastened over the hole, and pound the anchor into the hole with a hammer.
What are the dimensions of concrete anchor bolts?
Concrete metal impact anchors are available in two diameters – 3/16″ and 1/4″, as well as a range of lengths ranging from 7/8″ to 3″. The diameter of the anchor is the same as the diameter of the hole.

What is the definition of a concrete anchor?
Concrete anchors are meant to stay in place after put into a hole in the concrete.
What is the purpose of sleeve anchors?
The sleeve anchor works by pulling the cone-shaped stud end into the expander sleeve and wedgeing it outward to secure the anchor into the base material of concrete, brick, and block materials, based on the time-proven concept of expansion.
What are expansion anchors, and how do you use them?
Expansion anchors are fasteners that offer gripping force by expanding when used in masonry foundation material. Pre-expanded and un-expanded expansion anchors are the two types of expansion anchors. The pre-expanded expansion anchor is put into a predrilled hole and compresses before exerting effort to produce holding power.
What is the maximum weight that an anchor bolt can support?
The strength of toggles, anchors, and molly bolts is astonishing. On 1/2-inch drywall, a 1/8-inch toggle can securely support 30 pounds, whereas a 3/8-inch toggle can safely hold 50 pounds or more. When using any kind of drywall anchor, it’s important to know how they operate and which screw anchor is appropriate for a hollow wall.

I’m not sure how many anchor bolts I’ll need.
A minimum of two bolts are required for each bottom plate. Each end must have an anchor bolt within 12 inches. On a single bottom plate, the maximum separation between any bolts is 6 feet. My anchor bolts are six inches from the bottom plate’s end.

How to Remove a Concrete Anchor Bolt
- Determine the anchor bolt head’s size.
- Turn the anchor bolt counterclockwise with the socket to remove it from the concrete.
- On a tough bolt, use a bolt extractor.
- In the anchor hole, insert the awl.
- If none of the other options work, cut off the bolt head.
