About Embedment
Anchor Bolts (also called Wedge Anchors) get their holding strength from how far down into the Hole
the Anchor Bolt is installed (called embedment) and how forcefully the Expansion Sleeve presses into
the Concrete (based on how much torque is applied).
To get
enough
embedment, you have to understand
Effective
Embedment, which means the location
in the Hole where the Expansion Sleeve presses into the Concrete. This is where the Anchor Bolts
create holding strength; the further down into the Hole, the greater the holding strength.
(The technical definition of Effective Embedment is the distance from the surface of the base material
to the deepest point at which the load is transferred to the base material; the “base material” in our
case being the Concrete into which the Anchor Bolts are being installed.)
Some people confuse Effective Embedment with Nominal Embedment, which is how far down into the
Hole the bottom of the Anchor Bolt is.
As shown below, the two are not the same. Nominal Embedment does not tell you anything about the
holding strength of the Anchor Bolt.
Not necessarily to scale.
The Anchor Bolts shipped with your product have letters stamped into their tops, indicating how long
they are.
For example:
•
4.75 in / 120 mm long Anchor Bolts are stamped with a
G
.
•
6.3 in / 160 mm long Anchor Bolts are stamped with a
J
.
