About Effective Embedment
Anchor Bolts (also called Wedge Anchors) get their holding strength from how far down into the Hole
the Anchor Bolt’s Expansion Sleeve presses into the Concrete (called Effective Embedment) and how
forcefully the Expansion Sleeve presses into the Concrete (based on the width of the hole and how
much Torque is applied).
The further down into the Hole you get the Expansion Sleeve, the greater the Effective Embedment
and thus the greater the holding strength of the Anchor Bolt. The hole should be drilled the same width
as the Anchor Bolt with no wobbling. The correct amount of Torque is a range; too little Torque and
the Anchor Bolts hold with less strength, too much Torque and you could damage the Concrete and
lessen the Anchor Bolt’s holding strength.
Note: Some people confuse Effective Embedment with Nominal Embedment, which is how far
down into the Hole the bottom of the Anchor Bolt is. The two are
not the same; Nominal
Embedment does not tell you anything about the holding strength of the Anchor Bolt.
Make sure to carefully follow the specifications and instructions in Anchoring the Posts.
⚠ WARNING Use only the Anchor Bolts that came with your Lift. Only install your Lift on a
Concrete floor. Make sure to get the correct amount of Effective Embedment and
use the correct amount of Torque.
