Welcome back to Albany County Fasteners - Fasteners 101.
Today we're going to be reviewing Wedge Anchors, so lets 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 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.
