Welcome back to Albany County Fasteners – Fasteners 101.
I’m Bob and today, I’m going to show you how to installmasonry anchors.
But before we do that, please subscribe, like, and share myvideos.
Leave me a comment and we’ll get back to you.
Also hit the bell so you notified of new videos being uploaded.
So let’s getstarted.
I have here a masonry block.
You can see that we filled it with concrete already.
Basically to facilitate this video.
Ihave here different types of masonry anchors.
We pre-drilled all the holes already.
So I have the drop in anchor here.
Which I’m going to show you how to install.
I have a wedge anchor.
I’ll show you how to install that.
Sleeve anchor; I’ll show you how to install that.
And a nail masonry hammer anchor.
This one is a lag shield.
I have a separate video on this already.
We’ll put a link below that you can go to.
So I have a bunch of tools here that you’re going to need for each one of these types of anchors.
But for all of them you’re gonna need a hammer drill with the proper bit.
Which in this case is an SDS plus.
These hammer drills make the job so much easier.
So I recommend that you look into it.
If you’re just doing a simple project, look into renting one of these.
But basically you can buy one of these hammer drills for about 200 bucks.
Not a lot of money.
Then there are different types of masonry bits.
You have quad heads that have four cutters on them and then you have single carbide tips.
You can make that decision how much money you want to spend.
The quads obviously cost more money.
I have an hammer for.
all these basically.
Almost every one of them you’re going to need a hammer.
Phillips drive screwdriver.
And open end wrenches.
Along with a setting tool for the drop-in anchor.
So all these are gonna be used individually for these individual anchor applications So I have here a drop in anchor that I’m going to demonstrate the installation of.
Basically a drop in anchor is made upof a smooth surface, that you can see here, with a knurled portion down here with these slits in the steel to allow the lower part of the anchor to expand.
Inside there is a pin that we’ll be driving in, after we drop in into the hole, that we will set with this set tool.
This tool basically goes in and then we strike the top of this.
After we strike it, you won’t pull this out anymore.
This will be fixed in the concrete.
Onceyou put these in, there’s no taking them out.
You’re going to need the drop-in anchor, the hole to be drilled (which we pre-drilled already), and you’re gonna need a hammer So I’m going to drop the anchor in, like so.
I’m going to take the tool- Before that, I can put the screw in this and I can pull it out.
That’s the nice thing about drop in anchors, you can just drop them in.
Also make sureyour hole is clean of any debris.
All right I’m gonna take this screw out.
I’m gonna take the set tool and put it inside the anchor.
Now I’m going to strike it.
Then you get a solid sound all of a sudden which basically just set the anchor in place.
So if you took a screw and put it inthere, you can no longer pull this out anymore.
So whatever you’re fastening tothe concrete with a drop-in anchor, it could be this piece of wood, this is just for demonstration.
So we’re gonna install this wedge anchor.
They call it a wedge anchor becauseit has this wedge at the bottom.
Then it has this shield over the wedge that will wedge in the lower wedge.
As you tighten this up, this will pull on that shield.
You have to bang these in.
Once you bang this in past this point, you’re not gonna back it out again.
So the only way to get rid of a wedgeanchor, after you have put set it in place, is to take a hacksaw or sawzall and just cut it off.
So I’m gonna demonstrate now how to install a wedge anchor.
You can also see on the top here they have this section unthreaded.
They do that for a reason.
When you use the hammer, and this is a tool you’re gonna need, you’re also going to need an open endwrench or a ratchet wrench with a socket on it, when you strike this with a hammer that it’s not going to damage the threads.
Years ago they used to have the threads run all the way to the top.
Now they make it like a bull nose as they would call that.
That area that you see no more threads on the shank.
Now I’m just gonna hammer this down.
Now that triggers.
It’s hit the bottom.
You hear that solid sound.
So it’s hit the bottom.
You’re not gonna pull this out any further.
However, when I do start to tighten it’s gonna lift the wedge on the bottom of the wedge anchor into the sleeve.
Then it’s gonna tighten and expand that sleeve and it’s not going to come out.
So now it’s come up, I wouldsay to you, about 3/8 of an inch to 1/2 an inch.
It’s now wedged in tight.
I’m going to show you how to install this sleeve anchor now.
A sleeve anchor is basically a wedge anchor at the bottom here.
You can see the wedge and it has a sleeve on it This sleeve has slits in it and it also has these cross cuts in the bottom here.
As you’ll see.
These cross cuts are what grip the concrete when you install it.
This wedge down below, once it’s in place, pulls up into this area.
You can see the slit and the steel that will allow it to expand.
That’s basically how a sleeve anchor operates.
It’s pretty simple methodology.
Youcan install it this way.
You’ll need a hammer to install along with an open end wrench or a socket wrench or a ratchet to install this.
Then it engages and locks down the sleeve to the outside.
That’s the installation of a sleeve anchor.
I’m going to show you how to install this hammer drive anchor now.
Once you put these in, there’s no taking them out.
Basically these hammer drive anchors have a split down the center here, that you can see, and once this pin drives down it spreads that lower portion of the anchor.
These are mainly used in applying plywood to concrete floors.
Things like that.
I’m going to show you when installing this piece of wood into this block.
We put it through the material and then you’re gonna drive this pin down.
When I drive this pin down, it’s going to spread and it’s gonna lock that piece of wood in place.
I’m going to demonstrate that now for you.
You need a hammer for this application.
You can see I drovethat head down below the surface of the block.
So if you put wood flooring on top of this plywood instead of putting it on concrete, you now have a clean surface.
So you can install your wood flooring or carpet so that head does not stick up above the wood.
I hope you enjoyed this video.
I showed you how to install four different masonry anchors.
We’ll give you a link below for this lag shield.
Leave me a message or a comment.
If you need some with an installation, we’d love to help you.
Ask questions and we’ll respond with some answers.
Thanks for watching.
