  • 316 stainless steel for extreme chemical exposure and marine environments

We carefully make each wedge anchor with an expansion clip to prevent spinning and ensure proper installation. The anchors come packaged with the correctly sized nuts and washers for your convenience.

To install, drill a hole into the concrete using a carbide-tipped bit meeting ANSI standards. The hole diameter should match the anchor diameter for a snug fit. Clean the hole, insert the anchor, and hammer it in until the nut and washer are tight against the fixture. Use a wrench to tighten the nut to the specified torque value, and you will set your anchor!

When installing, make sure to follow the guidelines for depth, distance, and spacing to ensure safety and performance. Refer to our technical information charts for detailed specifications.

How to Install Wedge Anchors in Concrete

Installing wedge anchors is a straightforward process that can be completed in a few simple steps. Follow our guide below to ensure proper installation and optimal performance:

Step 1: Drill the hole

  • Use a hammer drill with a carbide-tipped drill bit that meets ANSI standards.
  • Make sure the hole diameter matches the size of the wedge anchor being used.
  • Make the hole deeper than the anchor will enter the concrete, at least 1/2". This ensures that the anchor embeds properly.

Step 3: Insert the wedge anchor

  • Place the washer and nut onto the threaded end of the anchor, ensuring the nut is threaded just enough to protect the threads during installation.
  • Insert the anchor through the fixture and into the drilled hole until the nut and washer are tight against the fixture.

Step 4: Expand the anchor

  • Using a hammer, tap the head of the wedge anchor until the nut and washer are snug against the fixture.
  • This action expands the wedge clip at the bottom of the anchor, creating a secure hold in the concrete.

Tips for Successful Installation:

  • Always wear appropriate personal protective equipment (PPE) when installing anchors, including safety glasses, hearing protection, and work gloves.
  • Ensure that the concrete is fully cured and has reached its specified compressive strength before installing wedge anchors.
  • Maintain the minimum edge distance and spacing between anchors as specified in our technical data sheets to prevent concrete splitting or anchor failure.
  • Do not overload the anchors beyond their rated capacities, as this can lead to failure and potential safety hazards.

Frequently Asked Questions

What are wedge anchors?

Wedge anchors are strong fasteners used to secure fixtures and equipment to solid concrete surfaces. These fasteners also go by the names concrete stud anchors or wedge bolts. They provide excellent holding power and are one of the most reliable anchoring solutions for concrete applications.

How do wedge anchors work?

Wedge anchors are mechanical fasteners that work by expanding a wedge-shaped clip at the bottom of the anchor when tightened. As you tighten the nut, it pulls the clip up against the sides of the drilled hole, creating a strong, secure hold in the concrete.

Can you use wedge anchors in hollow block or brick?

No, manufacturers design wedge anchors specifically for use in solid concrete. For hollow blocks or bricks, use sleeve anchors or toggle bolts instead of traditional anchors. These options work better with these materials.

What materials are wedge anchors available in?

Our wedge anchors are available in four main materials: Zinc-plated steel for dry indoor environments, Hot-dip galvanized steel for outdoor and moist conditions, 304 stainless steel for wet and corrosive environments, and 316 stainless steel for extreme chemical exposure.

How do I select the right size wedge anchor for my application?

When selecting a wedge anchor, consider the load requirements, the thickness of the fixture being fastened, and the thickness of the concrete. Refer to our technical data sheets for detailed information on holding values, embedment depths, and edge distances to help you choose the appropriate size anchor for your needs.

Can wedge anchors be removed after installation?

No, you cannot remove wedge anchors because they are not designed for that. Once installed and tightened, the wedge clip permanently expands, making removal impossible without damaging the concrete. For a removable anchoring solution, try adhesive anchors or mechanical expansion anchors with a removable nut.

What tools do I need to install wedge anchors?

To install wedge anchors, you will need a hammer drill, a properly sized carbide-tipped drill bit meeting ANSI standards, a hammer, and a wrench or socket set to tighten the nut. Always wear appropriate personal protective equipment (PPE) when installing anchors.

Are wedge anchors suitable for cracked concrete?

They work well in solid concrete, but may not be ideal for cracked concrete. If you have cracked concrete, talk to our technical support team to find the best way to anchor things securely.

Bob: Welcome back to Albany County Fasteners - Fasteners 101. Today we're going to be reviewing Wedge Anchors, so let's get started.

Zinc plated wedge anchors are used in interior applications and can be used on exterior applications. Hot dip galvanized wedge anchors are used for exterior applications. In fresh water, such as rain water, bay water, anything where you are using it in a non-salt water application. 304 Stainless is also used in fresh water. This will give you long lasting non-corrosive applications. So you would use stainless steel in an application where, you do not want to see any rust over a period of time or any surface corrosion.

316, 316 stainless is marked as 316. You'll find it marked on the nut. 316 Stainless. You'll find it on the washer, marked, as 316 stainless. And you'll see a marking on the bottom of a 316 stainless wedge anchor These wedge anchors can be used in saltwater applications. Such as docks, decks, anywhere you have, or a boardwalk; Anywhere you have a application where you are using salt water.

Okay, so we're going to prepare to install this half inch wedge anchor. We're going to take the nut off and the washer; we're going to use this blue tape as a marker to prevent from drilling through the concrete. I'm drilling into 8 into the concrete here so I have no worries, this is a two and three-quarter inch wedge anchor, so I have no worries about drilling through the concrete you never want to drill through the concrete so the bottom of the wedge anchor goes through the concrete. You always want to make sure you have enough thickness in concrete for the correct length of wedge anchor.

You want to have at least one inch sticking out of the top of the concrete, when you finish, so I'm going to take the wedge anchor and just put it up here and go to optimally 1 inch below and I'm going to put the tape where I want to stop from drilling. Stop the drill from continuing to drill it through the concrete if you drill the hole too deep it's not really going to hurt it if you were a little further let's say another half inch you just don't bang the wedge anchor too far down because once you push it down you will not, this piece down here creates the wedge once you put the wedge anchor into the hole and you pull up on it then wedges into the concrete preventing you from pulling the anchor out.

At that point you would have to use a Sawzall and cut it off to make it even with the concrete and then fill the hole push it down and fill the hole if you, you know, want to close up the hole. So now we're prepared and ready to drill a hole in the concrete and install the wedge anchor.

You just want to, tighten it to where it snugs up very tight. There you go, it is now that post base is now installed. Put the cover over it, put your post in, your deck is ready to go in place.

There you go, we've reviewed the proper installation for a wedge anchor. Along with proper materials to be used for your application.
