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.
How far apart should wedge anchors be?
10 hole diameters
The design of the expansion clip assures full contact with the masonry. Wedge anchors withstand temperature fluctuations well. For best performance, minimum anchor spacing should be 10 hole diameters and minimum edge distance be 5 hole diameters.
How do concrete wedge anchor bolts work?
The wedge anchor is inserted into a hole in concrete until the threads are below the surface of the concrete. The nut and washer are placed on the threads and tightened until finger tight. Using a wrench, the nut is then turned, which pulls the anchor up to wedge the clip between the stud and the wall of the concrete.
Which is stronger sleeve or wedge anchor?

What grade are wedge anchors?
Wedge anchors are available in many types of finishes and material grades. The four most common types are: zinc plated low grade carbon steel, hot dipped galvanized, 304 stainless steel, and 316 stainless steel.
How strong are concrete wedge anchors?
Wedge Anchor Holding Values
The holding power of the wedge anchor, as with any anchor, is always dependent on the quality of the concrete. As a rule of thumb, a safety factor of 4:1 or 25%, is generally accepted as a safe working load.
What are wedge anchors?
Wedge anchors are a unique type of concrete anchors, designed to anchor objects into concrete applications. Concrete Wedge Anchors are installed into a pre-drilled hole using the appropriate Concrete Drill Bit, where the wedge is expanded by tightening the nut.
