What is the difference between a sleeve anchor and a wedge anchor?
The wedge anchor, drop-in anchor and concrete strike anchor can only be used in solid concrete and have the highest & most consistent holding values in concrete. Concrete sleeve anchors can be used in concrete, brick or block but their holding values are less in terms of shear and pullout values.
Which is stronger sleeve or wedge anchor?
Sleeve anchors are fairly simple to use and are primarily used in brick or block. They can be used in concrete but are not considered as strong as a wedge anchor. So, for light to medium holding applications, a sleeve anchor is a good choice. There are two common types of sleeve anchors.

How long should my wedge anchor be?
As a rule of thumb, the space for the nut and washer is equal to the diameter of the wedge anchor being used. For example, if a 2×4 is being fastened to concrete with a 1/2” wedge anchor then the minimum length of wedge anchor would be 1-1/2”(2×4) + 2-1/4”(minimum embedment) + 1/2”(space for nut and washer) = 4-1/4”.
How deep should wedge anchor be in concrete?
2-1/2 inches
When installing a wedge anchor, it’s important to have a minimum of 2-1/2 inches embedded into the concrete. There should also be at least an inch exposed, enough for the attaching material to grab onto.
