Welcome back to Albany County Fasteners - Fasteners 101.
I'm Bob and today i'm going show you how to install a carriage bolt and remove it.
I have here my carriage bolt. Carriage bolts are typically installed with the carriage bolt, a washer and a nut, to follow.
Also you should know that to prevent carriage bolts from moving,
in the wood, have this square at the top that's notched.
It has no threads (on the square shoulder) so the threads on a carriage bolt do not run all the way to under the head.
So you can see that here and once i start drawing in
the nut, this will
prevent it from turning.
Also, you will need a hammer because sometimes,
its a little tight.
You could use a ratchet. I have an open end wrench here so that's what i'm going to use.
Use a ratchet if you'd like.
You can see it drawing that head right on in there. Nice and tight.
You can see it's pulling the head right in.
That's the installation of a carriage bolt so as you can see here the head is
As you can see here, the head is nice and flush with the wood. That's typically the way that
a carriage bolt should be completed and finished.
If you start to draw the head in, you can do that if you like, but its going to start to dimple the wood on the face.
Typically, you don't wanna see that. Now, if I want to remove this, all I would do
is loosen the nut,
bring the nut back to where its almost going to come off the carriage bolt.
Take a hammer, and just hit the opposite side (the nut side).
Bang it out. Back off the nut a little bit more, as much as you can.
Of course i'm doing this because this way,
so I don't ruin the actual carriage bolt and I can reuse the carriage bolt.
If you just don't care then just take the nut off and yank it out.
You can use the claw (backside of your hammer) like this.
To just pull it out. There you go: removed.
