A very highly used anchor out there,
wedge anchors. You basically drill a hole in the concrete to the circumference of the wedge anchor.
If it's 1/4 inch, then you drill a 1/4 inch hole. If it's 3/8 inch, then you drill a 3/8 inch hole.
How this works is: when you drill the hole into the concrete, and you lock down on this nut,
it starts to pull up on this wedge here that goes around the bottom diameter.
It starts to wedge in to this end and then it tightens up and doesn't pull out.
This is the strongest concrete anchor to use, as far as pullout goes.
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 freshwater.
Such as rain water, baywater, anywhere you are using it that is a non-saltwater application.
304 Stainless is also used in freshwater.
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 Stainless is marked as 316. You'll find it marked on the nut, 316 stainless.
You'll find it marked on the washer, 316 stainless.
And you'll see it marked 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 an application that uses saltwater.
So I have the wedge anchor. This is a 3/8 x 3 inch wedge anchor.
A pair of safety glasses.
Some blue painter's tape.
An open-end wrench.
A tape measure, a hammer...
...and my Bosch Bulldog Xtreme hammer drill,
and a pair of safety gloves.
These are all the items you're gonna need to install this wedge anchor.
Pretty simple. Pretty Straightforward.
You'll see on the bit here I put a piece of tape.
This is a 3 inch wedge anchor in length, from top to bottom.
I measured in at approximately 2 inches. You need at least 2 inches of grip into the concrete.
Typical concrete slabs are anywhere from 3 or 3-1/2 inches to 6 inches.
If you're in a house, you can guarantee that it's probably about 3 inches.
You never want to drill through your concrete and install your wedge anchor through the bottom.
Here I have 6 inches in this warehouse, so I have plenty of meat to work with.
I'm gonna go a little further. It's always good to go a little further when drilling the hole.
The reason is that you get dust down in the hole, so if it sinks below the wedge anchor to the bottom, you're fine.
It's no big deal.
If you don't, and you only go the 2 inches, you're gonna have to blow the hole out and clean it.
Going deeper than the 2 inches also allows you some wiggle room if you want to lower it a little more and not have as much thread sticking up.
Depends on your application.
